Paper Abstract

We focus on the noise characteristics of semiconductor lasers from a theoretical point of view. More precisely, we investigate the possibility of reducing amplitude noise in single-mode semiconductor lasers by forcing emission of sub-Poissonian light. Starting from a statistical laser model based on the photon density matrix equation (master equation) applied to a saturable medium, we have derived a fundamental condition for semiconductor lasers yielding to amplitude noise reduction. However, practical results reveal that sub-Poissonian light emission could only be achieved in the limit by specially designed semiconductor laser structures such as microcavity lasers. On the other hand, conventional bulk lasers must be disregarded as suitable sources for sub-Poissonian light emission.
