Uniform optical pumping design for 1.55 /spl mu/m VCSELs

Abstract

Numerical laser simulation of new active region design which provides more uniform gain using carrier blocking layers between the quantum wells is presented. The laser model includes calculations of optical carrier generation, carrier transport from the absorber layers to the quantum wells, quantum well gain, and optical field. The model is designed to compensate the non-uniform optical pumping of the quantum wells.
