Optoelectronics and Photonic Intelligent

Overview

Driven by the Internet of Things, cloud computing, artificial intelligence, Internet traffic volume, and computation-intensive applications, the accelerating growth of data requires high-speed and energy-efficient signal processing, transmitting, and detection. We are aiming to leverage the strengths of photonics and electronics to address these challenges using optoelectronic approaches. Our research cover quantum structure based semiconductor lasers, photonic integrated chips, photodetectors, meta-devices, and wide bandgap semiconductor photonic devices, with applications ranging from optical computing, optical communications, to optical sensing and imaging.
