Patent ID: 7675956

Claim:
A Vertical Cavity Surface Emitting Laser comprising: a semiconductor lamination structure including a first multilayer film reflector, an active layer having a light emitting region, and a second multilayer film reflector in this order over a substrate from the substrate side, wherein the semiconductor lamination structure has a pair of grooves provided with a region opposed to the light emitting region in between, 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, and one or a plurality of second oxidation layers including a second non-oxidation region provided in a region opposed to the light emitting region and a second oxidation region provided in a region not opposed to the light emitting region wherein the second oxidation layer is formed in a layer in which the grooves are not formed.
