OPTICAL MICRO / NANO RESONATORS AND DEVICES (OMND)

MF1 – 8:30am-10:00am
Lan Yang, Washington University, MO, USA, “Explore Whispering-gallery Resonators for a Versatile Sensor Platform”

SEMICONDUCTOR LASERS (SL)

MC2 – 10:30am-12:00pm
Cun-Zheng Ning, Arizona State University, US, “Semiconductor Nanolasers”
Abstract: Recent progress in semiconductor nanolasers will be presented in a tutorial manner, including semiconductor nanolasers using plasmonic structures as light confinement mechanism and 2D monolayer transition metal dichalcogenides as gain media. The potential relevance of such nanolasers to energy efficient usage will be discussed.

OPTICAL COMMUNICATIONS (OC)

MA3 – 1:30 PM – 2:30 PM
Erik Agrell, Chalmers University, Sweden, “Information-Theoretic Tools for Optical Communications Engineers”
co-author: Marco Secondini, TeCIP Institute, Scuola Superiore Sant’Anna, Italy
Abstract: Fundamental information-theoretic concepts are explained for nonspecialists, with emphasis on their practical usage. The notions of a “FEC threshold” and a “nonlinear Shannon limit” are critically reviewed, highlighting their limitations and possible alternatives.

PHOTODETECTORS, SENSORS, SYSTEMS AND IMAGING (PSSI)

TuB1: 8:30 AM – 10:00 AM
David Ting, Jet Propulsion Lab, USA, “III-V Semiconductor Unipolar Barrier Infrared Detectors”
Abstract: Rapid advances in III-V semiconductor bulk and type-II superlattice infrared material and the advent of the unipolar barrier infrared detector device architecture in the past decade have led to a new generation of high-performance infrared detectors and focal planes, providing a viable alternative to HgCdTe.

BIOPHOTONICS (BIO)

TuE2: 10:30 AM – 12:00 PM
Sylvain Gigan, Laboratoire Kastler Brossel, France, “Optical Imaging in Complex Biological Media: a Tutorial”
Abstract: Biological tissues are heterogeneous at the wavelength scale and scatter light strongly. While conventional microscopy techniques are limited to the first few hundred microns, a new arsenal of techniques have been derived, allowing to control multiply-scattered light, and opening the possibility to achieve deeper imaging.

OPTICAL FIBER TECHNOLOGY (OFT)

WD1: 8:30 AM – 10:00 AM
John Ballato, Clemson University, USA, “Novel Material Approaches to Advanced Optical Fibers and Fiber Lasers”
Abstract: This tutorial provides a road-map for the development of simple core/clad optical fibers whose enhanced performance – in particular, marked reductions in optical nonlinearities – is achieved materially and not through the more conventional present routes of geometrically complex fiber design.

CONSTELLATION SHAPING (SS)

WF2: 10:30 AM – 12:00 PM
Sethumadhavan Chandrasekhar, Nokia Bell Labs, NJ , USA, “Probabilistic Constellation Shaping: Key Enabler for Maximizing Transmission Capacity and Reach”
co-author: Cho, Junho

MICROWAVE PHOTONICS (MWP)

WE3: 1:30 PM – 2:30 PM
Alwyn Seeds, UCL, UK, “THz over fiber for high capacity wireless transmission”
Abstract: The requirement for increased data transmission rates for new wireless systems such as 5G and above places heavy pressure on currently allocated wireless spectrum. THz over fibre offers a technology with the potential to meet future needs for short range high data rate communications.
