Investigation of the dynamic behaviour of Laterally Coupled Diode Lasers by studying the noise spectrum and the small signal response

摘要

The study of the coupling phenomena and of the operation regions in laterally coupled diode lasers is a major key parameter for the understanding and development of these devices as a solution for the new optical communications systems. To understand the behaviour of these devices a complete study of their dynamics must be performed. In order to do so, in this paper a study of both the noise spectrum and frequency response is made. The aim of this study is to compare the performance of these devices as a single ridge laser and as a twin stripe operation.
