High-Speed Strained Quantum-Well Lasers and Optoelectronic Devices

摘要

We investigate research issues on strained quantum-well optoelectronic devices and their applications for navy needs. This work studies the fundamental physics in strained quantum-well devices such as Fabry Perot (FP) lasers, distributed feedback (DFB) lasers, and vertical cavity surface emitting lasers (VCSELs) through the development of theory and experiment. Integrated optoelectronic devices are also investigated for applications in wavelength division multiplexed (WDM) fiber optic communications systems such as wavelength tunability and wavelength conversion. In this work, we investigate the following areas: a. Comprehensive characterization of fundamental parameters of strained quantum- well lasers, b. Modeling and experiment of integrated laser/modulator devices, c. Modeling and experiment of VCSELs, d. Wavelength conversion using four-wave mixing and cross-phase/gain/absorption modulation, e. Optical gain theory for GaN-based blue-green quantum-well lasers.
