Research Statement:
Our current research activities include semiconductor nanolasers, nanophotonics, plasmonics, quantum-dot and quantum-well semiconductor devices, and suplerlattice photodetectors.

  1. Micro-Cavity Nanolasers:  We explore the concept of nanolasers using metal-cavities, surface plasmonics, optical field enhancement, and mode coupling to active materials such as semiconductor quantum wells and quantuim dots.

  2. Semiconductor 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.

  3. Type-II superlattice mid-infrared photodetectors: We design and fabricate antimony (Sb)-based type-II superlattice (T2SL) photodetectors. We investigate the defects in T2SL and characterize the detector performance using Fourier Transform Infrared Spectrometer (FTIR).

  4. High-speed 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.

  5. Slow 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 photonics.

Research Interests:
  • Photonics and Optolectronics, Nanophotonics, Semiconductor Lasers, NanoLasers, Nanoplasmonics.
  • Semiconductor Device Physics, Modulators, and Photodetectors; Physical and Quantum Electronics, Electromagnetics
Undergraduate Research Opportunities:
There are research opportunities on projects such as the characterization of semiconductor lasers, high speed modulation,  optoelectronics, and nanophotonics.

A strong motivation in research with background courses in physical electronics, quantum electronics, and electromagnetics will be desirable.
Graduate Research Opportunities:
Potential graduate students with a strong interest in semiconductor physics and optics are desirable. My group members conduct research on the theoretical design of quantum-well and quantum-dot semiconductor devices, fabrication of nanolasers, and device characterizations. We also have a project on the fundamental study of defects in type-II superlattice photodetectors. A strong background in semiconductor device physics is needed.
