High-Bandwidth Direct Modulation of Distributed-Feedback Quantum-Well Lasers

摘要

Wide-bandwidth microwave modulation of semiconductor strained quantum-well lasers using distributed feedback structures plays an important role in high bit-rate optical communication systems. It is therefore critical to conduct research on the device physics of strained semiconductor quantum-well lasers under high-frequency modulation and on the creation of new techniques to characterize high-speed quantum-well lasers. The goals of this project are (1) to design and fabricate high bandwidth distributed feedback quantum- well lasers using strain effects and (2) to combine microwave and optical measurement techniques to investigate the physics and device performance of quantum-well lasers under high-speed modulation conditions. The project is interdisciplinary in nature since optoelectronic device technology, microwave and optical measurement techniques will be introduced to the study of high-frequency modulation of quantum-well lasers for optical communication systems.
