Abstract :
This study presents the design and performance of self-assembled quantum dot (QD) vertical cavity surface emitting lasers (VCSELs) in a bipolar cascade configuration. The experimental VCSELs are grown by molecular beam epitaxy and consist of highly reflective AlxGa1-xAs (x = 0.0 and x = 0.9) doped DBR mirrors on a GaAs substrate, surrounding a GaAs-based microcavity active region containing stacks of InAs/InGaAs QDs.
