Photonic Integrated Circuits using Transparent Conductive Oxides: from Materials and Devices to System Integration

Photonic integrated circuits (PICs) hold the key to solve a myriad of grand challenges varying from data centers, high performance computing, 5G/6G network to machine learning and artificial intelligence, quantum computers and communication, and even autonomous driving. Unlike electronic integrated circuits that nearly exclusively rely on silicon, PICs have highly diverse requirement that can only be satisfied by heterogeneous integration of multiple optical and electronic materials. In this talk, I will discuss transparent conductive oxides as an emerging materials for PICs that can offer extremely high electro-optic efficiency on silicon photonics. Ultra-compact photonic crystal nanocavity and microring resonator modulators were demonstrated with unprecedented energy efficiency at a few fJ/bit. In the end, we will show some of our recent progress of on-chip wavelength division multiplexing PICs with large tunability.
