Vertical cavity surface emitting laser and method for manufacturing the same
Abstract:
A Vertical Cavity Surface Emitting Laser capable of being easily and inexpensively manufactured and stabilizing the polarization direction of laser light in one direction is provided. The VCSEL includes a semiconductor lamination structure including a first multilayer film reflector, an active layer having a light emitting region, and a second multilayer film reflectors, in this order over a substrate from the substrate side. The semiconductor lamination structure has a pair of grooves provided with a region opposed to the light emitting region in between, and one or a plurality of first oxidation layers including a first non-oxidation region provided at least in a region opposed to the light emitting region and a first oxidation region provided on each side face of the pair of grooves.
