Demonstrated is a vertical cavity surface emitting laser (VCSEL) formed by a passive half-wavelength cavity and a quarter-wavelength active gain region, wherein the said gain region resides in one of the VCSEL's distributed Bragg reflectors. The device concept invites extensive opportunities for innovation in the combinations of materials and gain region placements that may be used to construct surface emitting devices.
