Coupling Between Barrier and Quantum Well Energy States in A Multiple Quantum Well Optical Amplifier

Abstract

Multiple quantum well (MQW) optical amplifiers have recently been demonstrated. It has been shown that these MQW amplifiers have excellent characteristics such as high gain, large saturation power and low noise [1–3]. In addition to being excellent devices, they can serve as convenient tools to study the gain dynamics in an inverted MQW media.
