Broadly speaking, our group works in the area of “Meta-Optics & Optoelectronics Devices”. “Meta” is a Greek word meaning “beyond”. As its name suggests, we hope to build optical components with capability beyond what is currently available in conventional optics. To achieve this goal, we plan to combine knowledge in physics, optics, and materials science to explore new concepts to tailor light-matter interaction, now  at the sub-wavelength scale. We then develop the concepts into reality by fabricating and testing our designed devices in the laboratory.

Currently, we are most interested in building intelligent optical sensors, a device that may sense light amplitude, phase and polarization and many more, for you, me, and the robot. We are equally interested in developing unconventional, integrated nonlinear light sources emitting in the THz and EUV band that may be good for many things.
