1.5-µm Indium Phosphide-based Quantum Dot Lasers and Optical Amplifiers

Abstract

An overview will be given on the progress of quantum dot laser materials addressing the telecom C band and their high potential for the application in optical communication systems, where temperature stability of the device performance as well as a narrow linewidth emission plays an important role. Device results of quantum dot lasers and optical amplifiers will be shown, and the physical background discussed.
