Patent ID: 8824517

Claim:
A surface-emission laser device, comprising: an active layer; cavity spacer layers provided at both sides of said active layer; reflection layers provided at respective sides of said cavity spacer layers, said reflection layers reflecting an oscillation light oscillated in said active layer; a selective oxidation layer extending over all of the active layer and provided between a first location and a second location, oxidized portions of the selective oxidation layer extending to edges thereof, said first location being formed in one of said reflection layers and corresponding to a node of a standing wave distribution of an electric field of a fundamental mode of said oscillation light and said second location being formed adjacent to said first location in a direction away from said active layer, said second location corresponding to an anti-node of said standing wave distribution, wherein the selective oxidation layer has a thickness that is less than a distance from the node of the standing wave distribution corresponding to the first location to the antinode of the standing wave distribution corresponding to the second location.
