Abstract

New vertical cavity surface-emitting lasers (VCSELs) designs with improved threshold performance, device efficiency, and elevated temperature performance is described. The ability to define small devices with selective oxidation and the enhanced confinement led to low thresholds and high efficiency. On the other hand, larger devices have demonstrated high output powers with good wallplug efficiencies. The high efficiencies of selectively oxidized devices resulted in a lower threshold internal device temperature.
