Research

 

Note: We will update the projects with our recent progress soon.

 
Currently we focus on the silicon-chip based ultra-high-quality micro-resonators made from spin-on glass. The spin-on glass is a kind of glass obtained by curing a special liquid using sol gel or wet chemical synthesis to form a layer of glass. The main advantage of the spin-on glass is the easy tailoring of the nano/micro structure of the glass by controlled variation in the precursor solutions. It enables us to fabricate various micro/nano photonic devices from advanced materials with desired properties.
