We are currently interested in optoelectronic quantum-well devices and physics, semiconductor physics, and fiber optics.
Optoelectronics
Integrated optics
Quantum electronics
Strained Quantum-Well Lasers and Laser Physics
Terahertz Generation and Femtosecond Nonlinear Optics
Intersubband Quantum-Well Physics
Research Statement:
Our current research activities include high-speed optoelectronic devices for fiber optic communications and fiber optic sensors.
1. Semiconductor optoelectronic device physics: The devices include (a) semiconductor quantum-well devices using strained InGaAsP and InAlGaAs materials in integrated modulator-lasers, and (b) novel selectively oxidized vertical-cavity surface-emitting lasers (VCSELs) including theoretical modeling and experimental characterization. We also explore new semiconductor materials such as antimony-based systems for mid-infrared lasers and GaN-based systems for blue-green lasers.
2. High-speed modulation of lasers and Wavelength Division Multiplexing (WDM) research: High-speed microwave modulation of distributed-feedback lasers and VCSELs are investigated. Wavelength conversion for WDM applications using four-wave mixing, cross-gain and cross-absorption modulation are studied.
3. Fiber-optic sensors for civil structure applications: These projects are in cooperation with faculty in the Civil Engineering Department to design fiber optic sensors for transportation safety such as railroads and highway bridge applications. We have designed new fiber optic sensors for weigh-in-motion applications and the detection of railbreak and buckling for the Association of American Railroads.
