The past decade has seen accelerated progress in III-V semiconductor infrared photodetector technology. The advent of the unipolar barrier infrared detector device architecture has in many instances greatly alleviated generation-recombination (G-R) and surface-leakage dark current issues that had been problematic for many III-V photodiodes. Meanwhile advances in a variety type-II superlattices (T2SLs) such as InGaAs/GaAsSb, InAs/GaSb, and InAs/InAsSb, as well as in bulk III-V material such as InGaAsSb and metamorphic InAsSb, have provided continuously adjustable detector cutoff wavelength coverage from the short wavelength infrared (SWIR) to the very long wavelength infrared (VLWIR). The confluence of these developments has led to a new generation of versatile, cost-effective, high-performance infrared detectors and focal plane arrays based on robust III-V semiconductors, providing a viable alternative to HgCdTe (MCT).

Circulating exosomal miRNA represents a potentially useful class of bloodborne biomarkers for cancer. We present the initial proof-of-concept of an approach in which gold nanoparticle tags are prepared with thermodynamically optimized nucleic acid toehold probes that displace a oligonucleotide and reveal a capture sequence that is used to selectively pull down the target-probe-nanoparticle complex to a photonic crystal (PC) biosensor surface. By matching the surface plasmon resonant wavelength of the nanoparticle tag to the resonant wavelength of the PC nanostructure, the reflected light intensity from the PC is dramatically and locally quenched by the presence of each nanoparticle.
The talk described the optical operating principles of Photonic Resonator Absorption Microscopy (PRAM), the thermodynamic design of DNA toehold probes, and our first results demonstrating the detection limits, selectivity, and dynamic range of the assay.

Communications networks and systems are seeing extreme increases in network traffic which is growing at the tremendous rate of 30% per year. It is estimated that the energy and cost requirements will increase tenfold in coming year. But this progress is not sustainable from an ecological and economic point of view. However, this information explosion can be dealt with, using the integration of very small photonic components on very high density Photonic Integrated Circuits (PICs). The technolgoical advancements in PICs have made them a popular choice for components of next generation networks. Silicon being the evident choice due to its high availability, mature fabrication technology, and low cost has attracted components on a chip. At the same time, the unique, material properties and direct bandgap of group III-V materials have huge potential in applications like laser amplifiers, modulators, and detectors. Due to robustness, flexibility, reliability, and performance of PICs, many commercial solutions are now available for a variety of applications.

Abstract: Success in a photonic startup company requires constant attention to the balance between risk and opportunity. These risk / opportunity decisions involve many different areas, technical, marketing, financial, organizational and psychological, among others. Some of these decisions are very specific to photonic startup issues but the balance of opportunity and risk touches on a broad range of aspects of life, of course.
This presentation discussed the general nature of risk and opportunity and from these general ideas will then derive recommendations for effective risk management methods in photonic startups. The presenter did this through examples drawn from his own experience and from the experience of others that have influenced him strongly

Abstract: The excitement of nanowire research is due to the unique electronic and optical properties of these nanostructures. Both axial and radial heterostructure nanowires have been proposed as nano‐building blocks for the next generation devices, which are expected to revolutionise our technological world. The unique properties stem from their large surface area‐to‐volume ratio, very high aspect ratio, and carrier and photon confinement in two dimensions. These nanowires are usually grown by the so‐called vapor‐liquid‐solid mechanism, which relies on a metal nanoparticle to catalyze and seed the growth. An alternative technique to grow the nanowires is by selective area growth technique, where a dielectric mask is first patterned on the substrate prior to growth. In this talk, I will present an overview of compound semiconductor nanowire research activities at The Australian National University. The optical and structural properties of binary and ternary III‐V nanowires including GaAs, InGaAs, InP and GaAsSb nanowires grown by metal‐ organic vapour phase epitaxy will be presented. Various issues such as tapering of the nanowires, compositional non‐uniformity along nanowires, crystal structure, carrier lifetime and polarization effect will be discussed. I will also present our results of III‐V nanowires grown on Si substrates which are of great interests for the integration of nano‐optoelectronic devices on Si platforms. Our results of enhancing the quantum efficiency of nanowires by using plasmonics are promising to improve the performance of nanowire devices. Finally, the results from our nanowire lasers, photodetectors, solar cells and photoelectrodes for water splittng will be presented.

[Seminar] Leveraging Advances in Computational Electrodynamics to Enable New Kinds of Nanophotonic Device Design
Who: Dr. Ardavan Oskooi, Founder and CEO of Simpetus
When: Thursday, October 29th 12:00 pm
Where: ESB 2001
Snacks & Coffee will be provided.
Ardavan Osooki is offering to meet personally with interested students and researchers to discuss how to use his electromagnetics FDTD software for your specific simulations, or how to how to program an FDTD software from scratch, as he has done.
If you are interested in a one-on-one meeting with him, please email to Tanya Das firstname.lastname@example.org with your availability on Thursday, October 29th, and we will get back to you with a meeting time.
Abstract: Advances in computational electrodynamics have the potential to enable fundamentally new kinds of designs in nanophotonic devices which are based principally on complex, non-analytical wave-interference effects. Powerful, flexible, open-source software tools have now been made available for use in large-scale, parallel computations to model the interaction of light with practically any kind of material in any arbitrary geometry. These recent developments in computational capability make possible the investigation of various emergent structures and physical phenomena that were previously beyond the reach of pencil-and-paper analytical methods as well as less versatile and even less accessible commercial software tools. Here, I demonstrate how such advances in finite-difference time-domain (FDTD) methods for computational electromagnetism via an open-source software package known as MEEP can lead to entirely new designs for light trapping in nanostructured thin-film silicon solar cells as well as light extraction from nanostructured organic light-emitting diodes (OLEDs). In the last part of this seminar, I will provide a live demonstration of launching MEEP simulations on an on-demand high-performance computing (HPC) cluster in the cloud through our startup, Simpetus. Simpetus provides a holistic solution to the three main challenges of using simulations for research and development: 1) no software licenses or installation, 2) no hardware acquisition or maintenance and 3) technial support from the experts. The mission of Simpetus is to propel computational simulations to the forefront of photonics research and development.

Abstract: The talk will describe the theory, design, fabrication, and the experimental results of an effort that led to a new type of hybrid Si/III-V semiconductor (SCL) laser with a linewidth below 1 KHz. This result is nearly 3 orders of magnitude better (smaller linewidth) than that of commercial SC lasers.
Other key parameters relevant to coherence such as the phase/amplitude coupling constant, α, and the relaxation resonance frequency are reduced by more than an order of magnitude. The fabrication employed is CMOS compatible making the new laser integrable with electronic circuits and potentially enabling a new generation of communication, time-keeping, and sensing applications.

Where: Eng. Sciences Building (ESB), Room 2001
Abstract: The surging progress in silicon photonics over the past decade has been driven by its potential application in low cost, high bandwidth, wavelength-division multiplexed short reach optical interconnect. Despite significant advances, numerous technical challenges remain, such as the control of resonant devices, the implementation of large swing optical modulators, the management of polarization, the need for improved variation tolerance, an effective means for efficient and broadband fiber-to-chip optical coupling, and approaches to electronic-photonic integration.
In this talk, I will provide an overview of my group’s progress in addressing these issues in silicon-based photonic platforms. Photonic devices and integrated circuits implemented in standard silicon-on-insulator photonic platforms and a custom silicon nitride-on-silicon platform will be presented. I will describe microring modulators and filters that circumvent conventional limits, the first polarization rotator-splitters and controllers in standard silicon photonic platforms, grating couplers with record-setting bandwidths and insertion losses, and our ongoing efforts in electronic integration. The work paves the path toward very large- scale photonic integrated circuits and terabit-scale optical transceivers.

Abstract: Today’s fiber-optic communication networks span the globe, delivering broadband information across all market segments and connecting massive datacenters, businesses, and individual user’s homes. As such, optical networks must operate reliably and efficiently when transporting the massive information capacity of the Internet, allowing networks to adapt to growing and changing demand flows and occasional interruptions. Wavelength-selective switches (WSS) have been instrumental in fulfilling this role, enabling all-optical spectral routing of individual wavelength-division multiplexed (WDM) communication channels at network nodes.
The recent introduction of space-division multiplexing (SDM) to the optical communication domain with new fiber types, in order to economically support the exponentially growing capacity, necessitates complementary components for implementing SDM-WDM optical networks. SDM is typically realized with either multi-core or few-mode fibers and great capacity achievements have been demonstrated to-date in each fiber solution. Wavelength-selective switching functionality for these two fiber types has recently been introduced. A joint- switching WSS concept has been realized for multi-core fibers, enabling information to be encoded and routed on the SDM-WDM optical network as a spatial super-channel (single wavelength channel spanning multiple cores). This spatial super-channel routing concept with joint-switching WSS also extends to few- mode fibers. Hence a single WSS can then be used in analogous fashion to the single-mode fiber networks, thereby heralding the cost-savings benefits of SDM. A WSS with direct few-mode fiber interfaces has been demonstrated with the few-mode beams routed in free-space just as the single mode beam does in a conventional WSS. A study on the pass band filtering effect and mode mixing due to the spectral switching of dispersed components revealed the spatial-spectral interplay in the mode-dependent loss attributes of the few- mode fiber WSS. Such advanced WSS prototypes will serve the next generation transport networks when SDM is fully adopted by carriers.

Abstract: Microscopy is usually performed in a laboratory on carefully prepared, very thin samples and achieves resolutions of better than a micrometer. Medical imaging, by contrast, is usually performed on sizeable portions of the living human body, and resolutions are rarely better than 1 millimeter. Over the last decade, there has been great progress in applying optical microscopy techniques to the human body in a medical setting. This push has been led by optical coherence tomography (OCT), which is now in mainstream use in ophthalmology and is gaining acceptance in cardiology. In this talk, 3D microscopic imaging deep inside tissue using the OCT microscope in a needle will be described. Needle delivery makes optical imaging possible in many tissues previously inaccessible to optics. Aimed to be broadly accessible, this talk will describe the underpinning photonics and guided-wave optics design and fabrication needed to make high-quality micro-imaging possible. Technical advances such as realization of ultra-small needle probes, extended imaging depth of focus, handheld micrometer-resolution tracking, and multimodality needle probes combining OCT with fluorescence, and with elastography will be presented. It will describe how such probes are built into photonic systems and where they are being applied, such as in breast cancer surgery, as well as how the technology may evolve and where it may be applied in the future.

Summary: Photodetectors continue to play a crucial role in fiber optic communication systems and microwave photonics as applications demand higher bandwidths, larger power levels, and increased spectral efficiencies. High-speed, high-power photodetectors are needed as conventional top-illuminated p-i-n photodiodes cannot achieve the requisite bandwidth-efficiency products, while output power levels cause a move to side-illuminated waveguide photodiodes, photodiode arrays, and novel epitaxial layer structures. Furthermore, photodetectors incorporated into photonic integrated circuits enable more complex receiver architectures for the detection of advanced modulation formats guaranteeing the highest performance and packing density at the lowest cost.
In my talk, I provide a brief introduction to photodiode fundamentals, considerations of material systems and basic structures. I present state-of-the-art 145 GHz-waveguide photodiodes and high-power photodetector arrays that have been successfully operated at bitrates as high as 160 Gbit/s and discuss the development of an integrated dual-polarization coherent receiver that has become a key component in today’s 100 Gbit/s and emerging 400 Gbit/s fiber optic links. I cover novel device structures and photodiode arrays that enabled photonic generation of highly linear microwave signals at record-high output power levels. This includes heterogeneously integrated InP-based photodiodes on silicon that achieved the highest saturation current-bandwidth products on a silicon photonics platform to date.

Prof. John Bowers, Dr. Simon Poole & IPS President Sudha Srinivasan after Dr. Poole's lecture.
Dr. Simon Poole gave a fantastic lecture, attended by researchers from many fields beyond photonics.
With the remorseless growth in demand for telecommunication services, the capacity of optical fiber links first exceeded the capabilities of electronics, requiring the introduction of wavelength division multiplexing, and is now approaching a fundamental limit.
This limit is due to a trade-off between the familiar Shannon limit at low signal powers, and nonlinear effects at high powers. Before considering the implications of the capacity crunch when demand finally hits this limit, this lecture will review the technological achievements which took the industry from its first commercial service with the Dorset (UK) police in 1975 through to the 10 Tbit/s systems of today.
