Our current research activities include semiconductor nanolasers,
nanophotonics, plasmonics, quantum-dot and quantum-well semiconductor
devices, and suplerlattice photodetectors.
lasers: We explore the concept of nanolasers using surface plasmonics,
optical field enhancement, and mode coupling to active materials such
as semiconductor quantum wells and quantuim dots.
optoelectronic device physics: The devices include (a) quantum-well and
quantum-dot devices using strained semiconductor materials in
integrated modulator-lasers, and (b) InGaN blue-green lasers and LEDs.
superlattice mid-infrared photodetectors: We design and fabricate
antimony (Sb)-based type-II superlattice photodetectors. We investigate
the defects in T2SL and characterize the detector performance using
Fourier Transform Infrared Spectrometer (FTIR).
modulation of lasers: High-speed microwave modulation of semiconductor
lasers and wavelength conversion using quantum-well and quantum-dot
devices are investigated. Low-chirp high bandwidth nanolasers are
explored for future photonic integrated circuits.
and fast light using quantum-well and quantum-dot semiconductor optical
amplifiers: We have demonstrated slow and fast light at room
temperature using coherent population oscillation and four-wave-mixing
effects. The slow light devices have potential applications as optical
buffers, dispersion compensation devices, as well as microwave
