Abstract

We describe the fabrication and operation of vertical cavity surface emitting lasers (VCSELs) by pulsed optical pumping. The VCSELs structure is a ZnSe-ZnS MQWs with a Fabry-Perot cavity. The stimulated emission in ZnSe-ZnS MQWs VCSELs is observed at thresholds of 3.6MW/cm² with the wavelength near 440nm at 77K. On the basis of the absorption and photoluminescence spectra in the ZnSe-ZnS MQWs, we attribute the major physics mechanism for the stimulated emission of ZnSe-ZnS MQWs VCSELs to exciton and exciton interactions.
