AMPLITUDE OR INTENSITY STABILITY IN SEMICONDUCTOR LASERS

Abstract
For the physicians, noise measurements on semiconductor laser diodes (SC-LD) provide accurate informations on stability and fundamental parameters which stand into rate equations describing the interaction between photons and electrons. But intensity fluctuations worry users of SC-LD coupled to optical fibres, in amplitude modulation analog transmission techniques. In this paper, we first consider how the noise is caracterized. Then we describe the measurement techniques and give results on different types of SC-LD.
