Vertical-cavity surface-emitting lasers with spatially adjustable DBR reflectivity to enable free-space photonic repeaters - IEEE Xplore
Abstract: We have created bidirectional high-performance top- and bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) from a single epitaxial wafer. Using a spatially selective oxidation ...

Single transverse mode operation of electrically pumped vertical-external-cavity surface-emitting lasers with micromirrors - IEEE Xplore
We report an electrically pumped vertical-external-cavity surface-emitting laser (VECSEL) that is designed for wafer-scale fabrication. Single-mode continuous-wave operation is demonstrated at a ...
