Semiconductor laser with integrated optical elements
Patent
·
OSTI ID:5915621
This patent describes a semiconductor laser having at least one optical element integrated therein comprising, a plurality of contiguous semiconductor layers on a substrate, the layers and substrate forming a semiconductor body, pumped portions of at least one of the layers forming an active region for lightwave generation, means for injecting current into the active region to produce the lightwaves, means for obtaining optical feedback of the lightwaves to achieve lasing operation, the feedback means defining a resonant cavity in the semiconductor body, and means within the semiconductor body for optical waveguiding of the lightwaves.
