Modulation Enhancement Through Resonant Microwave-Photonic Co-Design
(2023)Traditional photonics design results in devices that are very sensitive to the environment and imperfections, bulky, and often inefficient, thereby prohibiting scaling. Photonics inverse design can lead to optimal devices that are much better than state of the art on many figures of merit, fully compatible with foundry based fabrication, and can even enable new functionalities for photonics. Examples include error free transmission in ...Conference Paper -

Subthreshold VO₂ vertical switches for large-bandwidth millimeter-wave and sub-terahertz detection
(2022)2022 47th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz)Non-linear impedance characteristics of VO 2 offer solutions to highly sensitive radio-frequency (RF), millimeter-wave (mm-wave), and terahertz (THz) detectors. We demonstrate high-speed broadband sensibility of miniaturized VO 2 switches by utilizing the nonlinearity close to the abrupt insulator-to-metal transition (IMT). We apply an intensity modulated sub-THz signal to the 2-terminal devices inside a coplanar waveguide (CPW) and detect ...Conference Paper -
