Low-threshold 1.57-μm VC-SEL's using strain-compensated quantum wells and oxide/metal backmirror

We present an electrically-pumped long wavelength vertical cavity surface-emitting laser (VC-SEL) using strain-compensated multiple quantum well gain medium and an oxide/metal backmirror. Design flexibilities such as using oxide/metal mirrors are possible because of the exceedingly high optical gain provided by strain-compensated multiple quantum wells. The… (More)
