Bistable Vertical-Cavity Surface-Emitting Laser. Structures on GaAs and Si Substrates

Abstract

The research performed under this contract centers around the study and development of semiconductor microcavity lasers in the GaAs/AlGaAs/InGaAs material system. In addition, theoretical modeling is developed to study the influence of small cavities on laser performance. In the course of this work we have developed and studied bistable vertical-cavity surface-emitting lasers (VCSELs) fabrication processes to realize low-threshold microcavity lasers, and detailed modeling describing the influence which the semiconductor microcavity exerts over the spontaneous emission and lasing characteristics. I believe that our best and most interesting results have been achieved in our last year of funding. Since they build heavily on our earlier two years of research I will focus this final report on these results achieved in the final year.
