报告题目：Transparent Conductive Oxide Integrated Photonics
主持人：陈 沁 教授
摘要：Transparent conductive oxide (TCO) materials have attracted escalating 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, TCO materials can be deposited with high quality using DC- or RF-sputtering on various platforms including silicon photonics, which also possess long term stability. Therefore, TCO materials are fully compatible with silicon photonics and has the potential to be readily integrated with existing 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, including energy-efficiency silicon-TCO photonic crystal nanocavity modulators, silicon-TCO microring resonators with ultra-large E-O tuning efficiency, and broadband plasmonic-TCO electro-absorption modulators. 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 operation bandwidth above 25 GHz.
