Spiking Neuron in a Photonic Integrated Circuit

Monday, 01 November 11:00 – 11:30

Speaker: Hsuan-Tung, Princeton University, USA

Photonic spiking neurons represent an important class of optical computing. We have fabricated a laser neuron that uses excitable laser dynamics to achieve biologically-inspired spiking behavior, and demonstrated its compatibility for larger scale system integration.”

Industrial Applications of the Monocular Stereo Camera as an Omnidirectional Imaging and Ranging Device

Monday, 01 November 12:00 – 12:30

Speaker: Rei Sakaibara, Hitachi, Japan

To realize a compact and cost-efficient omnidirectional imaging and ranging device, we developed a monocular stereo camera, which consists of two axisymmetric hyperbolic mirrors, a lens, and an image sensor. These mirrors enable omnidirectional imaging and ranging with a single image sensor, thereby achieving compactness and the low cost. In this talk, we present experimental results of a prototype such as human tracking, 3D modeling, and SLAM. Based on these results, we also discuss applications on autonomous driving, robot teleoperation, and remote inspection

Multi-milijoule Infrared Pulses from a Laser Wakefield Accelerator

Monday, 01 November 14:00 – 14:30

Speaker: Amina Hussein, University of Alberta, Canada

The formation of a plasma wave during laser wakefield acceleration (LWFA) results in a co-propagating refractive index gradient that produces time dependent frequency shifts in the driving laser pulse, extending its spectral content to the mid-infrared. We present high-resolution spectral measurements of pulses extending to the mid-infrared from a LWFA using tailored-density plasma targets. Pulses contain up to 15 mJ of energy and 3D simulations demonstrate good focusability. Infrared pulses generated via LWFA are unique and highly versatile in that they are simultaneously produced and inherently synchronized with energetic electrons beams and hard X-ray sources. Further, statistical analysis of variations in spectral features with laser and plasma conditions indicate that the conditions necessary for wavelength and energy tunable sources may be achieved using adaptive control and/or machine learning techniques with high-repetition rate laser systems.


Computational 3D/4D holographic Imaging

Tuesday, 02 November 12:00 – 12:30

Speaker: Ni Chen, King Abdullah University, Saudi Arabia

Holography is a well-known three-dimensional (3D) imaging technique because it encodes 3D information into one single intensity image. However, retrieving 3D information from holograms is a challenging inverse problem. This talk shows two advanced computational 3D holographic imagining techniques: the joint optimization framework for dynamic 3D imaging and the model-based Holo-Net for fast 3D imaging. Both take the domain-specific priors of the systems and objects into computational reconstruction algorithms. Specifically, the former takes advantage of the deformation between volume frames, and the latter feeds physical priors into deep network design. These physics-informed studies outperform conventional imaging techniques and may promote the development of computational imaging.

The Power of LabelFree Holographic 3D Imaging in Flow-cytometry

Tuesday, 02 November 15:00 – 15:30

Speaker: Pietro Ferraro, Institute of Intelligent Systems CNR, Italy

The advent of holographic label-free technology combined with microfluidic lab-on-chip platforms is expected to explore new cellular frontiers with real fallout in the life sciences, thus bringing beneficial effects on human health, the environment and the biotech industry. In fact, the distinctive and unique features of digital holographic microscopy will provide soon to construe new disruptive paradigms in flow cytometry based on single cell 3D imaging based on full staining-free morphological analysis


Molecules in Intense XFEL Fields

Tuesday, 02 November 16:00 – 16:30

Speaker: Daniel Rolles, Kansas State University, USA

X-ray free-electron lasers can produce short-pulse and short-wavelength radiation at unprecedented intensities and enable studies of nonlinear X-ray – matter interactions. This talk will review X-ray multiphoton ionization of atoms and molecules and discuss applications for ultrafast imaging of nuclear and electronic dynamics during chemical reaction in the gas phase.

Cavity Optomechanical Sensors and the Effect of Noise and Drift on Inertial Sensing

Wednesday, 03 November 09:30 – 10:00

Speaker: Lia Li, University College London, UK

How sensitive is too sensitive? A rich variety of micron to nano-scale cavity optomechanical devices such as levitated nanospheres and suspended photonic crystals are sensitive to displacements smaller than the width of a single atom. Researchers can exploit this coupling to detect tiny forces like those generated by gravitational waves, or to sensitively track inertial forces to derive orientation and position for navigation. In this talk I’ll describe steps towards modelling optomechanical inertial sensors at both the classical and quantum limit, taking into account noise and drift through analysis of Allan deviations, and aligning analysis to sensing application.

The Search for the Optimum Information Rate and Symbol Rate Of PS-QAM Systems to Enable Highly Efficient Optical Transmission

Wednesday, 03 November 12:00 – 12:30

Speaker: Olga Vassilieva, Fujitsu Network Communications Inc, USA

The flexibility and adaptability of optical coherent transponders play a key role in the dynamic optimization of capacity and reach. These features are vital in the design of highly efficient optical networks that can cover wide range of applications from datacenter interconnect (DCI) to Metro to Long Haul. Modern commercial transponders support probabilistic constellation shaping technology, which can provide fine granularity in capacity and reach. The next generation of optical transponders will support finely tunable symbol rates. These flexible symbol rates can provide an additional opportunity to further optimize capacity and reach compared to the traditional methods. In this talk, we show how to use finely tunable symbol rates and the fine granularity in capacity and reach to customize constellation for a target application.

Interactive Generation of Full Color 4K Image Hologram

Generalized Collective Mode Spectroscopy and Quantum Probes of Quantum Matter from a Theory Perspective

Thursday, 04 November 14:00 – 14:30

Speaker: Prineha Narang, Harvard University, USA

My group research focuses on how quantum matter behaves, particularly away from equilibrium, and how we can harness emergent effects in these systems. In this context, I will focus on our newly introduced approaches to describe excited-states in quantum matter, including electron-electron and electron-phonon interactions beyond leading order, and predicting emergent states introduced by external drives. Next, I will discuss a class of exotic collective excitations which are unique to time-reversal symmetry breaking (TRSB) superconductors and propose a number of means by which these excitations can be experimentally detected, introducing a notion of “collective mode spectroscopy” of TRSB superconductors1. Building on this, I will present avenues in using electromagnetic cavities and resonators to probe and control quantum matter discussing methods to treat electrons, photons and phonons on the same quantized footing, accessing new observables in strong light-matter coupling 2,3. Understanding the role of such strong light-matter interactions in the regime of strongly-correlated electronic systems is of paramount importance to fields of study across condensed matter physics, quantum optics, and quantum chemistry 4-6. Our theoretical and computational framework7-9 opens new routes by which the important problem of strongly-correlated quantum dynamics may be studied in these fields. Finally, I will give an outlook on driving correlated quantum systems far out-of-equilibrium to control the coupled electronic and lattice degrees-of-freedom and connect these recent predictions with ultrafast THz experiments underway.

Cylite Delivers Hyperparallel OCT into Ophthalmic Markets

Thursday, 04 November 15:00 – 15:30

Speaker: Steve Frisken, Cylite, Australia

Cylite has developed a proprietary Hyperparallel Optical Coherence Tomography HP-OCT volume imaging and metrology technology. The snap-shot volume acquisition is able to overcome motion artefacts that have plague in-vivo volume acquisition and enables simultaneous metrology of the key structures of the eye, critical for refractive and cataract surgery. An accurate 3-D imaging instrument is well positioned to broaden the applications of OCT in the ophthalmic market. The wide acquisition volume imaging of both the anterior and posterior segments of the eye, with an intuitive volume visualization of pathologies, provides a valuable clinical tool for patient education and surgical planning
