Vanadium Dioxide Phase Transition Modeling and Bias Control for Photodetection
VANADIUM DIOXIDE PHASE TRANSITION MODELING AND BIAS CONTROL FOR PHOTODETECTION by Zhongnan Qu A thesis submitted in conformity with the requirements for the degree of Master of Applied Science The Edward S. Rogers Sr. Department of Electrical & Computer Engineering University of Toronto © Copyright by Zhongnan Qu 2020 Abstract Vanadium Dioxide Phase Transition Modeling and Bias Control for Photodetection Zhongnan Qu Master of Applied Science The Edward S. Rogers Sr. Department of Electrical & Computer Engineering University of Toronto 2020 Vanadium dioxide (VO2) is a transition material that demonstrates phase transitions between the insulator and metallic states when under thermal, electrical or optical stimuli. It is a promising material for novel devices, for instance, switches, volatile memory, oscillatory neural network units, and photodetectors. Despite being a long-standing interest in the field of condensed matter physics, the numerous observed properties of VO2 remain insufficiently explained, which impedes the progress of its utilization for electronic devices. This thesis develops theoretical explanations and corresponding analytical and numerical models that fit our fabricated VO2 devices. This thesis also investigates the feasibility of utilizing VO2 as photodetectors and develops a bias control circuit with low-cost off-the-shelf circuit components, enabling repeated operations despite the hysteresis effect, demonstrated the potential of VO2 to be integrated with existing electronics. ii Acknowledgments I thank my supervisor, Prof. Joyce Poon for granting me this opportunity as well as providing me the support and environment to conduct this research. Her guidance and encouragement throughout my master’s study have allowed it to be an enriching and fruitful experience. I thank Junho Jeong and Dr. -
Michal Lipson Named 2021 John Tyndall Award Recipient
Michal Lipson Named 2021 John Tyndall Award Recipient WASHINGTON – The Optical Society (OSA) and the IEEE Photonics Society have named Michal Lipson, Eugene Higgins Professor of Electrical Engineering and Professor of Applied Physics at Columbia University, USA the 2021 John Tyndall Award recipient. Lipson, the first woman to receive the award since it was established in 1987, is recognized for “fundamental and technological advances in integrated photonic devices." “A trailblazer in the field, Michal Lipson’s groundbreaking research led to the development of the first gigahertz silicon modulators, demonstrating that silicon photonics could produce active devices,” said 2020 OSA President Stephen Fantone. “The Tyndall Award is a well- deserved testament to her visionary work in nanophotonics.” "Michal Lipson is a leader, a pioneer and a giant in the field of nanophotonics for her contributions to the physics and applications of light confining photonics structures”, added IEEE Photonics Society President Carmen Menoni. “The IEEE Photonics Society is delighted with her recognition by the Tyndall Award." The award, one of the top honors in the fiber optics community, is named for John Tyndall, a 19th century scientist who was the first to demonstrate the phenomenon of total internal reflection. It recognizes an individual who has made pioneering, highly significant, or continuing technical or leadership contributions to fiber optic technology. The Tyndall Award will be presented to Lipson at OFC 2021 (Optical Fiber Communication Conference and Exhibition), the world’s leading conference and exhibition for optical communications and networking professionals, 6 to 10 June 2021 in San Francisco, California, USA. Corning, Incorporated sponsors the award, which consists of a specially commissioned glass sculpture that represents the concept of total internal reflection, a scroll and an honorarium, and it is jointly presented by The Optical Society and the IEEE Photonics Society. -

Demonstration of Chip-Based Coupled Degenerate Optical Parametric Oscillators for Realizing a Nanophotonic Spin-Glass

Jang1, Xingchen Ji 3, Yun Zhao3, Bok Young Kim 1, ✉ Michal Lipson 1,3 & Alexander L. Gaeta 1,3 1234567890():,; The need for solving optimization problems is prevalent in various physical applications, including neuroscience, network design, biological systems, socio-economics, and chemical reactions. Many of these are classified as non-deterministic polynomial-time hard and thus become intractable to solve as the system scales to a large number of elements. Recent research advances in photonics have sparked interest in using a network of coupled degenerate optical parametric oscillators (DOPOs) to effectively find the ground state of the Ising Hamiltonian, which can be used to solve other combinatorial optimization problems through polynomial-time mapping. Here, using the nanophotonic silicon-nitride platform, we demonstrate a spatial-multiplexed DOPO system using continuous-wave pumping. We experimentally demonstrate the generation and coupling of two microresonator-based DOPOs on a single chip. Through a reconfigurable phase link, we achieve both in-phase and out-of-phase operation, which can be deterministically achieved at a fast regeneration speed of 400 kHz with a large phase tolerance. 1 Department of Applied Physics and Applied Mathematics, Columbia University, New York, NY 10027, USA. 2 School of Electrical and Computer Engineering, Cornell University, Ithaca, NY 14853, USA. 3 Department of Electrical Engineering, Columbia University, New York, NY 10027, USA. 4These ✉ authors contributed equally: Yoshitomo Okawachi and Mengjie Yu. -
