Research Overview

The research in our group focuses on mesoscopic physics and optoelectronics especially in the platforms of optical waveguides and microcavities. Ultrahigh-Q optical microcavities have become intriguing testbeds for light-matter interactions owing to their strong confinement of light field. The miniaturized nano-/micro-fibers are demonstrated with many intriguing properties, such as the strong light field confinement, large surface evanescent fields, tunable dispersion and mechanical configurability. We hope to explore the fundamental light-matter interactions at the nano-/micro-scale, and realize novel optical and optoelectronic applications.
