Patent ID: 8340148

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 oscillating light oscillated in said active layer; and a current confinement layer restricting a region of said reflection layer when injecting a current into said active layer; and a suppression layer suppressing higher-order mode components oscillated in said active layer, wherein said suppression layer comprises a first selective oxidation layer provided between a first location in said reflector layer corresponding to a node of a standing wave distribution formed by an electric field of said oscillation light and a second location in said reflection layer adjacent to said first location in a direction away from said active layer, said first location corresponding to said node of the standing wave distribution, said second location corresponding to an anti-node of said standing wave distribution, said current confinement layer comprises a second selective oxidation layer different from said first selective oxidation layer, and a distance between said active layer and said first selective oxidation layer is larger than a distance between said active layer and said second selective oxidation layer.
