Method And Device For Producing Laser Emission

摘要

A method for producing laser emission, including the following steps: providing a layered semiconductor structure that includes a substrate, a lower reflector and a semiconductor collector region disposed over the substrate, a semiconductor base region disposed over the collector region, and a semiconductor emitter region disposed over the base region; providing, in the base region, at least one region exhibiting quantum size effects; depositing collector, base, and emitter electrodes respectively coupled with the collector, base, and emitter regions; disposing an insulating upper reflector over at least a portion of the emitter region; and applying electrical signals with respect to the collector, base, and emitter electrodes to produce laser emission from the base region in a vertical resonant optical cavity defined between the lower reflector and the insulating upper reflector.
