Abstract :
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.
