Abstract

A comprehensive study has been conducted on ultra-broadband optically pumped quantum dot (QD) reflective semiconductor optical amplifiers (QD-RSOAs). Furthermore, little work has been done on broadband QD-RSOAs with an optical pump. About 1 μm optical bandwidth, spanning 800 nm up to 1800 nm, is supported for the suggested device by superimposing nine groups of QDs. It has been shown that the device can be engineered to amplify a selected window or a group of desired windows. Moreover, the operation of the device has been thoroughly investigated by solving the coupled differential rate and signal propagation equations. A numerical algorithm has been suggested to solve these equations. As far as we are concerned, a broadband optically pumped QD-RSOA that can operate as a filter has been introduced.

摘要

已经对超宽带光泵浦量子点（QD）反射半导体光放大器（QD-RSOA）进行了全面研究。此外，关于光泵浦宽带QD-RSOA的研究工作很少。通过叠加九组量子点，所建议的器件支持约1μm的光带宽，范围从800nm到1800nm。结果表明，该器件可以设计成放大选定的窗口或一组所需的窗口。此外，通过求解耦合的微分速率和信号传播方程，对该器件的运行进行了深入研究。已经提出了一种数值算法来求解这些方程。就我们所知，已经引入了一种可以用作滤波器的宽带光泵浦QD-RSOA。
