THURSDAY, 17 NOVEMBER 2022 10:30 AM-12:00 PM PT
1st Place ($1000 USD)
Tobias Beckerwerth, Fraunhofer Heinrich Hertz Institute, Germany
“High-Speed Waveguide Integrated Avalanche Photodiode on InP”
We present a waveguide integrated avalanche photodiode for high-speed operation. Its sophisticated structure comprising a fully undepleted absorber and an additional drift-layer, reducing the transit time significantly. The device shows high external responsivity of 0.61 A/W at unity gain for a wavelength of 1550 nm, while the bandwidth is up to 37 GHz at a gain of M=1.5.
2nd Place($600 USD)
Morgan Turville-Heitz, University of Wisconsin-Madison, USA
“High-Power Mid-Infrared Quantum Cascade Lasers for Free-Space Communications”
Short-cavity (L=1.5 mm) 1st-order, metal/semiconductor-grating DFB QCLs, emitting at λ~ 4.7 μm, are found to operate to 166mW CW and 1.5 W peak-pulsed powers. Modeling of the device performance has been correlated with experimental findings, showing good agreement with calculated threshold-current densities.
3rd Place($300 USD)
Naoki Yamaguchi, University of Tokyo, Japan
“Coherent Doppler LiDAR using Novel MEMS-based Optical Phased Array Scanner”
This paper presents the first implementation of a novel MEMS-based optical phased array scanner in Coherent Doppler LiDAR. Through live experiments, simultaneous velocimetry and random-access scanning are demonstrated to an accuracy of 0.65 m/s with 63.4⁰ FOV.
Honorable Mention($150 USD)
Essam Berikaa, McGill University, Canada
“EDFA-Free Net 500 Gbps Transmission over 2 km Using a Thin-Film Lithium Niobate IQM”
We demonstrate the transmission of 124 Gbaud 32QAM (144 Gbaud 16QAM) on a single polarization in the C-band over 2 (10) km without optical amplification under the 2.4×10-2 SD-FEC threshold using a thin-film lithium niobate IQ modulator; representing a net data rate of 515 (480) Gbps
Honorable Mention($150 USD)
Lachlan Goulden, The University of Sydney Nano Institute (Sydney Nano) and Institute of Photonics and Optical Science (IPOS), The University of Sydney, Sydney, NSW, Australia
“On-Chip Quasi-Light Storage for Long Optical Delays”
We demonstrate quasi-light storage based on stimulated Brillouin scattering in a chalcogenide waveguide on a photonic chip. One nanosecond long optical pulses were delayed by up to 500 ns greatly exceeding previous on-chip demonstrations.
1st Place ($125 USD)
Russell Schwartz, George Washington University
“Reducing Latency in Sensing for Optical Convolutional Neural Networks”
2nd Place ($100 USD)
Nusrat Alim, UNSW CANBERRA
“Visible Colors Realized by TiO2 Nanostructure”
3rd Place ($75 USD)
Michele Paparella, University of Montpellier
“Analysis of the optical coupling between 2.3 μm GaSb diode lasers and passive waveguides for monolithic integration on Si platforms”
