Presenter: Professor Alan Wang
Title: Heterogeneous Integration of Transparent Conductive Oxides with Silicon Photonics

About the Presentation
Transparent conductive oxide (TCO) materials have attracted tremendous research interests for integrated photonic devices in recent years due to the extraordinary perturbation to the refractive indices achieved either through oxygen vacancy doping or electrical gating. In addition, high quality TCO materials can be deposited using DC- or RF-sputtering on various platforms including silicon platforms. Therefore, TCO materials are fully compatible with silicon photonics and promise unprecedented potentials for heterogeneous integration with silicon photonic integrated circuits (PICs). In this talk, I will review recent research progress in my group for the development of TCO-gated silicon photonic devices to achieve ultra-high energy efficiency, high speed photonic devices, including photonic crystal nanocavity modulators and microring resonators with ultra-large E-O tuning efficiency. We also achieved 5Gbit/s E-O modulation speed and will also discuss the strategy to further improve the energy efficiency to atto-joule/bit and implement large-scale integration for data centers.

The event is finished.
