Fiber Lasers

& Photonic Device Lab.

Welcome to FLPD!

We are interested in advanced ultrafast fiber lasers/amplification systems, various nonlinear optical phenomena and nano photonic devices based on low dimensional materials such as carbon nanotube (CNT), graphene, and transition metal dichalcogenides (TMDs) for the applications to the military, display/semiconductor industry and optical communications.
