Title:
Nanophotonics for Optical Long Data Storage
Abstract:
We are entering an age of information explosion. The exponential growth of the data size and computing resources has motivated scientists and engineers to further develop the big data storage technique into long data, which requires continuous recording and reading large amount of data for a long period of time. This stringent requirement represents an insuperable challenge to the current big data centres. The advance of nanophotonics has provided a variety of avenues for light–matter interaction at the nanometer scale by nanometer-confined optical probes in nanocomposite materials, which enables disruptive techniques to meet the future demand of long data storage. In this talk, we demonstrate the super-resolution photoinduction-inhibited nanolithography (SPIN) technique enabled ultra-high capacity optical recording for big data. More importantly, we increase Young’s modulus of the nanocomposite materials by two orders of magnitude through the in-phase incorporation of ceramic components, leading to an enhanced lifespan of recorded bits toward 500 years. This technique opens new path way of nanophotonics-enabled long data storage for continuous recording and reading over centuries.

Title:
Plasmonic Enhanced Solar Cells
Abstract:
There has been an increasing interest in plasmon-induced enhancement of solar cells and more recently in the direct generation of photocurrent, using the Localized Surface Plasmon Resonance (LSPR) of gold (Au) metal nanoparticles. This paper will discuss the three mechanisms of plasmonic enhancement in solar cells; scattering, hot-electrons and Plasmonic Resonant Energy Transfer (PRET). It will show how the size, shape and the surrounding dielectric environment of the Au nanoparticles are important in determining the enhancement mechanism. Recent research using Au nanoparticles embedded in Titanium Dioxide (TiO2) to increase the photocurrent, through the generation of hot-electrons, will be presented. The results showed photocurrent generation at wavelengths longer than the semiconductor band gap due to photon absorption by the Au. Results obtained for Au nanoparticles embedded in Copper Zinc Tin Sulphide (CZTS) will also be presented, which show an increase in photocurrent due to PRET.

Title:
InGaN/GaN Nanowire LEDs and Lasers
Abstract:
The existing planar group-III nitride epitaxy for light-emitting diode (LED) is grown on thermal- and lattice-mismatched sapphire (α-Al2O3). For the case of InGaN-based light-emitters, this typically resulted in threading dislocation densities in the order of 106-108 cm-2. The epitaxy strain in the two-dimensional (2D) InGaN quantum-well led to decreasing luminescence efficiency as the indium composition increased towards ~25% and beyond, constituting the green gap in nitride-based light-emitting diodes (LEDs). The challenge in achieving efficient InGaN QWs in the green gap stems from the strong spontaneous and piezoelectric polarization-fields induced electron-hole wavefunctions separation. Addressing the LED efficiency droop issue, the polarization-field reduction was achieved employing modified active region design, epitaxy lift-off, and growth on semipolar substrate. In order to simultaneously circumvent the lattice-mismatch limitation, efficiency-droop, and green gap issues for covering the UV-VIS wavelength range, without resorting to bulk GaN substrates, researchers turned to investigation of nanowires grown on silicon, attractive for industry uptake. These nanowires can be grown treading-dislocation free even at high indium composition with reduced quantum-confined stark effect (QCSE), thus improving quantum efficiencies. The reduced efficiency-droop blue, green, red and white LEDs grown using MBE demonstrated the potential of nanowires array emitters for practical applications, beyond basic research. Currently, challenges for quantum-disks nanowires emitters include: (a) quantum efficiency improvement in long and short wavelength nitride LEDs covering the InN (0.7 eV) to GaN (3.4 eV) spectrum, (b) phonon confinement in these laterally discontinuous nanostructures, leading to junction heating and reduced heat dissipation, (c) surface states due to the high specific surface of these 3D nanostructures. In this talk, we will present our work on nanowires emitting in green-to-infrared wavelength range [1-5]. Approach in enhancing heat dissipation, as well as surface states passivation in InGaN/GaN quantum-disk nanowires LEDs will also be presented.

Title:
Silicon Quantum Photonics for Single Photon Sources and Wavelength Conversion
Abstract:
Quantum key distribution offers provably secure communication, with the security against eavesdroppers guaranteed by the laws of quantum physics. While current implementations are limited in maximum distance and in bit rate, it is in principle possible to surpass these limitations by using high-quality photonic devices to generate and manipulate single photons. In this talk, I will discuss progress at the University of Sydney in building single-photon sources and a single-photon wavelength converter based on nonlinear silicon waveguides. In particular, an integrated quantum splitter is considered, where pairs of identical photons are generated in a highly nonlinear silicon ring-resonator, and quantum interference is then used to split these photons into separate waveguides so that they can be manipulated separately. Also, four-wave mixing in a silicon nanowire is used to shift the wavelength of a single photon level signal between telecommunication WDM channels.
Biodata: Bryn Bell was born in Windsor, England. In 2009 he received a Masters degree in Physics from the University of Oxford, UK, and in 2014 he completed a PhD at the University of Bristol, UK in experimental quantum information and single photon sources in photonic crystal fibre. Since early 2015 he has been a CUDOS postdoctoral researcher at the University of Sydney with interests in photonic chip based quantum technologies and quantum light sources.

Title:
High-Speed Optical Wireless Communications for In-Building Personal Area Networks
Abstract:
Optical technologies have long been investigated to provide efficient backhaul transport for mobile networks and have the potential to also provide direct wireless transmission to support ultra-high-speed connectivity. In this paper, we review our recent progress in optical wireless communication systems utilizing infrared free space link for in-building personal area networks. We have previously proposed and demonstrated a high-speed infrared optical wireless system incorporating localization function that enables limited mobility. Our system is based on line-of-sight transmission but with slightly diffused beam incorporating much larger footprint compared to traditional free-space optics where tight alignment is vital to maintain connectivity. We have experimentally demonstrated a multi-gigabit/s full-duplex free space transmission link for 10 Gb/s downlink and 2 Gb/s uplink. Optical wireless communication is susceptible to physical shadowing as direct line-of-sight is a necessity. To overcome the impact of physical shadowing, we have demonstrated a 10 Gb/s optical wireless link using space-time-block-coding which is robust to shadowing effect.

Title:
Fabrication of Integrated Optical Waveguides for Use in New Quantum Technologies
Abstract:
A century ago the first quantum revolution defined our understanding of atomic and subatomic physics. A few decades later this understanding lead to a technological revolution where the semiconductor, the laser, and the optical technologies that enable our current digital information age were created. Today, quantum research is primed for the next revolution in systems technology; ‘Quantum 2.0’ promises solutions for unhackable communications (quantum cryptography), navigation and sensing (atomic clocks), and solving complex analytical problems at the speed of light (quantum computing).
In Quantum 2.0, photonics represents a stable and established technology platform upon which new quantum systems can be built. Photonics enables the generation of new wavelengths for interaction of light and matter, single photons and integrated optical circuits for quantum information processing, and optical fibre networks for the long-haul transmission of quantum information. For commercial adoption, photonics will provide an important interface between emerging quantum products and our existing telecoms networks and digital infrastructure.
At the University of Southampton we are developing new manufacturing technologies in silica-on-silicon and periodically-poled lithium niobate to enable the fabrication of scalable integrated optical components as the building blocks of Quantum 2.0; in particular our focus is the development of processes suitable for transfer and adoption by industry. We will report on our progress in this area and discuss recent results enabled by our devices.

Title:
Fabrication of Integrated Optical Waveguides for Use in New Quantum Technologies
Abstract:
A century ago the first quantum revolution defined our understanding of atomic and subatomic physics. A few decades later this understanding lead to a technological revolution where the semiconductor, the laser, and the optical technologies that enable our current digital information age were created. Today, quantum research is primed for the next revolution in systems technology; ‘Quantum 2.0’ promises solutions for unhackable communications (quantum cryptography), navigation and sensing (atomic clocks), and solving complex analytical problems at the speed of light (quantum computing).
In Quantum 2.0, photonics represents a stable and established technology platform upon which new quantum systems can be built. Photonics enables the generation of new wavelengths for interaction of light and matter, single photons and integrated optical circuits for quantum information processing, and optical fibre networks for the long-haul transmission of quantum information. For commercial adoption, photonics will provide an important interface between emerging quantum products and our existing telecoms networks and digital infrastructure.
At the University of Southampton we are developing new manufacturing technologies in silica-on-silicon and periodically-poled lithium niobate to enable the fabrication of scalable integrated optical components as the building blocks of Quantum 2.0; in particular our focus is the development of processes suitable for transfer and adoption by industry. We will report on our progress in this area and discuss recent results enabled by our devices.

Title:
Nonlinear Optics in Integrated Liquid-filled Optical Fibers
Abstract:
Optofluidic systems based on liquid-filled optical fiber represent an alternative way for nonlinear optics in optical fibers, in particular due to the large nonlinearity of some liquids and specific molecular dynamics of anisotropic molecules. We will present recent results, especially toward supercontinuum generation in an integrated nonlinear optofluidic fiber arrangement.

He studied the influences of molecular collisions on the vibrational and rotational Stimulated Raman spectra of gas by CARS (Coherent anti-Stockes Raman spectroscopy). In 1996, he got a permanent position in the Université de Bretagne Occidentale, Brest (France), where he studied the heterogeneous catalysis of molecules chemisorbed on surface in UHV chamber by the MIES (Metastable Impact Electron Spectroscopy) and UPS (ultraviolet Photoelectron Spectroscopy) techniques. He joined in 2002 the optics department of FEMTO-ST institute, in Université de Franche-Comté, Besançon (France). He studied the spatiotemporal dynamics of spatial soliton arrays in Kerr waveguides generated by Modulation Instability, and the slow-light process on spatial solitons induced by Raman scattering. He is currently focusing on nonlinear processes in liquid core optical fibers filled with highly nonlinear liquids.

Title:
Plasmonic gold nanoparticles for nano- and bio-photonic applications
Abstract:
Plasmonic gold nanoparticles have been at the centre of attention in nanoscience and technology due to their extraordinary optical and physical properties. Recent advances in its application to high density optical storage and cancer therapeutic agents utilize its strong linear and non-linear absorption, near-field enhancement and plasmon-coupling in 1- 20 nm regime. While many applications are being demonstrated, fundamental understanding of these advances is still lacking. Where does the metal luminescence come from? How does the shape play a role in the luminescence? What are the material limitations? Is the stability of particle shape critical in success of these applications? How does the reshaping of these particles occur? In this talk, I will present recent spectroscopic studies of single gold nanoparticles (luminescence, scattering and correlation spectroscopy) at Optical Nanomaterial Spectroscopy group in addressing these important questions for future success of their application.

Title:
Weaving our way towards a new generation of fibre-optic chemical sensors based on spider silk.
Abstract:
From the spider's perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of preys on its web. Indeed, this primeval material has been shaped over hundreds of millions of years by spiders to create a myriad of silk fibre types with different toughness, elasticity, stickiness depending on its attributed function in the web. From a human perspective, scientists are currently working in harnessing all the extraordinary properties of this material for applications spiders would never thought of, from biocompatible tissue engineering (enhancement of skin regeneration and nerve guides) to biodegradable electronics and development of specialist textile and composites. However, the potential of using spider silk fibre for chemical sensing has been overlooked. In this presentation, we will explore the potential of using spider silk as a new type of fibre optic chemical sensor in a fully bio-inspired approach.
Biodata: Kenny Hey Tow received his M.Sc degree from the University of Montpellier II, France in 2009 and his Ph.D degree in Physics from the University of Rennes 1 in February 2013. His Ph.D research work, performed at FOTON laboratory in Lannion (France), was focused on developing Brillouin lasers, more particularly made from microstructured chalcogenide fibres, and the study of their noise properties. He then joined the Group for Fibre Optics at the Swiss Federal Institute of Technology of Lausanne (EPFL), Switzerland as a postdoctoral researcher. He is currently carrying research on specialty fibres (photonic crystal fibres, chalcogenide and polymer fibres, etc.) for the development of new optical fibre sensors and laser sources.

Title:
Highly Efficient PPLN Waveguide and Their Applications
Abstract:
In this talk, we will review recent advances in periodically poled LiNbO3 (PPLN) waveguides and their applications. The high power tolerance and high efficiency of directly bonded waveguide allowed us to explore x(2) based phase sensitive amplifier which exhibits low noise and phase squeezing features. The wide-range transparency of the waveguide also enabled highly efficient mid-IR generation which is useful for gas sensing. The progress in waveguide fabrication, packaging, and challenges in several applications will be reviewed.

Title:
TiO2 doped ZnO Nanorod Arrays by Chemical Bath Deposition
Abstract:
Defects in ZnO semiconductor play an important role in its properties and applications. Ti is a good transition element in ZnO structure due to its small ionic size and high valence electrons. There were very limited studies on the roles of Ti in ZnO in promoting dopant related emissions for any potential applications. In this work TiO2 doped ZnO nanorod arrays have been synthesized using simple, low temperature and inexpensive chemical bath deposition procedures on silicon substrates. The FESEM images showed high quality nanorods were uniformly grown on the substrate surfaces. No defects issues were observed at the nanorods surface. The XRD patterns confirmed that the prepared samples possessed hexagonal wurtzite structure with preferred growth in the c-axis direction. The samples exhibited high (002) intensity with slight shift toward the low angle compared with undoped ZnO. The PL spectrum exhibited a strong enhancement in near band edge emission with a blue shift as compared with undoped ZnO. The results showed that TiO2 can play a vital role in improving the properties of ZnO nanorods prepared using low temperature, inexpensive, simple chemical bath deposition method.

TMR&D Efforts to Uphold the PON Technology Research in Malaysia
Abstract:
Research on Passive Optical Networking (PON) technology has been started since the mid-2003s, where P2P was launched by TM R&D management. However, significant development activities occurred from the early 2006 where a few projects were funded by Telekom Malaysia. Two different technologies were studied, based on IEEE and ITU-T (EPON and GPON respectively) standardization, but more focus was given to EPON technology. While the general concepts (architecture, optical distribution network, wavelength plan, and application) are the same for both EPON and GPON, their operational protocol is very much different. Before TM officially launched UNIFI on March 2014, TM R&D product for Fibre To The School (FTTS) based on EPON has been deployed in 2009.

Title:
Rare-earths with Ceramic Oxides Doped Nanostructured Multielement Glass based Specialty Optical Fibers for Photonic Applications
Abstract:
A strong material related research on development of different varieties of specialty optical fibers through nano-structuring of the doping host composition of core glass materials by MCVD with solution doping technique is going for manipulating and enhancing light-matter interactions to improve fundamental device properties of fiber laser, optical amplifier and broad-band light sources as they are the most essential optoelectronic devices at modern communication system. Accordingly researches on nanostructured optical fibers elaborated by incorporating dielectric metallic nanoparticles or silicon nanoparticles or semiconductor nanoparticles or phase-separated dielectric nonmetallic nanoparticles or quantum dots in an amorphous matrix have attracted much attention. The basic composition of nano-engineering glass is based on multielements doped into silica glass matrix consisting of certain ceramic oxides such as Al2O3, ZrO2, Y2O3 along with rare-earths such as Er2O3, Yb2O3 and Tm2O3 incorporating minor amount of P2O5 for making of fiber laser and optical amplifier. Here P2O5 serve as a nucleating agent to accelerate the growth of formation of phase separated nano-particles particles upon heating through thermal perturbation owning to the higher field strength difference (>0.31) between Si4+ and P5+ . Importance of ceramic oxides (Al2O3, ZrO2, Y2O3 ) for making of nano-engineering glass based optical fiber involves reduction of the clustering phenomena of rare-earths ions strongly with increase in the solubility of rare-earths compare to pure silica glass matrix as well as increase of the refractive index of the doping host glass of rare-earths ions due to the larger sizes of Al, Zr and Y cations with strong ionic polarizability. Such kind of glass host also increases the optical non-linearity because of the formation of large number of nonbridging oxygens (NBO) into phase-separated nano-particles region since non-bridging oxygens have high ionicity and are easily distorted by applied optical-electric field as the defects generated from the phaseseparated nano-particles. These nanoparticles dispersed in a silica matrix based optical fibers show large nonlinear optical properties and offer a great potential for optical amplification , lasing as the rare earth ions doping concentration can be higher than in an amorphous medium. Moreover, the energy transfer process can be observed in such RE doped nanoparticles containing optical fiber that leads to exotic luminescence properties. In my invited talk elaborated the results of the following different varieties of nano-engineering glass based specialty optical fibers:- (1) Nano-engineered yttria-alumina glass based thulium-doped fiber for fiber laser at NIR region. (2) Nano-engineered yttria stabilised zirconia-allumina silica glass based erbium-doped fiber for use as graphene based mode-locked fiber laser (3) Ytterbium doped nano-engineered germanium-zirconia-silica glass based single mode fiber for making of all-fiber laser amplifier system to produce the NIR SCG as well as visible and ultraviolet (UV) (4) Nano-engineered erbium doped Yttrium stabilized zirconia-calcium-alumina-phospho silica glass based optical fiber for thermal regenerated grating operation above 10000 C. (5) Ag and Bi metal doped nano-engineered yttria-alumina-silica glass based optical fiber for making of broad band light source in visible region. (6) Ytterbium doped nano-engineered multi-element glass based optical fiber with low photodarkening phenomena. In this work, we present an overview of the our recent research progress on ceramic oxides doped nanostructured multi-element glass based specialty optical fibers with doping of rare-earths and metals through MCVD in combination with solution doping technique by giving detailed fabrication methods, related mechanisms, luminescent properties, lasing phenomena, photodarkening behaviour, amplification properties etc. The potential photonic applications of these fibers are also mentioned briefly.

Photonics has been used for some time to image, analyse or manipulate biological materials and has moved in many areas from a laboratory tool to real life applications. Biophotonics is, for example, used in medicine to investigate tissue and blood, and is used to diagnose and treat diseases. In the agricultural field many of the measurement problems are similar in principle, but often different constraints apply, like price or speed, which offer new challenges. Our work focusses on horticultural applications, in particular the prediction of internal quality of produce. Visible and near infrared spectroscopy can measure the chemical composition or quality of fruit and vegetables and has been successfully applied to high-speed produce graders and in the orchard. The measured attenuation, which is affected by absorption as well as light scatter, provides information on bulk properties but does not give easy insight of internal distribution, defects or physical parameters like firmness. In this presentation I will give an overview of our work towards extending traditional NIR spectroscopy to measure firmness, internal defects or internal properties of produce.

1.55-mm Bi-birectional Free Space Optical Transmission with High-Capacity
Abstract:
In this talk, we design and demonstrate two free space optical (FSO) schemes for high-speed transmission. The first scheme is bi-directional FSO communication with 2 ´ 4 ´ 10 Gb/s capacity in dense wavelength division multiplexing (DWDM) system with a transmission distance of 25 m. The measured power penalties for bi-directional, four-channel DWDM FSO communication are less than 0.8 dB and 0.2 dB, compared with the back-to-back link and the uni-directional transmission system, respectively. Several effects of environmental factors on the FSO performance are investigated and analyzed. The second scheme is hybrid optical fiber (OF) and free space optics (FSO) link in outdoor environments such as bridge. A sensor head is used for monitoring the condition of the bridge, and in the case of the bridge being damaged the transmission path is changed over from OF to the FSO link to ensure data link connectivity. Power penalty variation between OF and FSO paths is < 1 dB. In both cases, the single-mode-fiber components are used in the optical terminals for both optical transmitting and receiving functions.

Title:
Structured light as a versatile photonic tool
Abstract:
Recent advances in laser technology give us unprecedented control over spatio-temporal properties of light. Here I will show two examples of how one can exploit such structured light. First, I will focus on THz emission from ionizing multi-color femtosecond pulses in gas. The properties of the generated THz radiation are extremely sensitive to the pump pulse configuration, thus it appears possible to tailor via the pump pulse configuration. For the second example I will switch to material processing with intense femtosecond laser pulses. By spatio-temporal shaping of the driving pulse one can optimize the energy deposition in the material, relevant to, e.g., fs-surgery in ophthalmology.

At the same time, Stefan Skupin was heading the Junior Research Group for Computational Nonlinear and Relativistic Optics at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany. The main focus of his ongoing research is the interaction of high-intensity, ultra-short laser pulses with matter, and, in particular, its numerical modeling. His research thrusts include
- novel light sources from high-intensity laser matter interaction,
- nonlinear ultra-short pulse generation and propagation,
- pattern formation, solitons, vortices and topological excitations,
- Bose-Einstein condensation phenomena,

Coding Techniques for Distributed Fiber Sensors based on Brillouin Scattering
Abstract:
Fiber-optic fully distributed Brillouin strain and temperature sensing is based on the strain- and temperature-dependence of Brillouin frequency shift and the ranging technique, allowing measurement of their local change across a fiber. Raising signal-to-noise ratio (SNR) of the Brillouin sensing system plays a crucial role in the improvement of its performance; increase in SNR can be used to enhance the distance range, to reduce the measurement time, and to attain higher spatial resolution. In this talk, we will review our recent work on pulse coding techniques to measure Brillouin scattering with higher SNR. In contrast to the way of just raising the peak power, the pulse coding can improve SNR of the Brillouin scattering signal without suffering from unexpected signal distortion due to nonlinear effects such as Raman scattering. However, straightforward implementation of the pulse coding technique could lead to another distortion in the decoded signal especially for high spatial resolution measurement. The distortion is brought about by damping effects of the acousticwave which causes the Brillouin scattering, and thus is never observed in previous Rayleigh scattering based sensors. So, we will discuss approaches to implement the pulse coding to Brillouin fiber sensors, minimizing that distortion.
