Semiclassical analysis and experimental investigations of vertical-cavity surface-emitting laser noise

摘要

Abstract: Noise and amplitude squeezing performances of vertical cavity semiconductor laser are investigated theoretically and experimentally. Theoretical results based on a newly developed semiclassical model predict very good performances for VCSELs as squeezed states generator. However, they also emphasize out the strong limitation of these performances by phenomena such as thermal roll-off, polarization instabilities, gain suppression and spatial hole burning.In addition, experimental investigations have been performed with VCSELs emitting in the 770 nm range. A good correspondence between theoretical results and experiments has been found, with the additional influence of lateral modes and the polarization of the emitted light. Finally, conclusions on possible improvements and on the optimized laser parameters are drawn. !31
