Patent ID: 7978739

Claim:
A surface emitting laser element, comprising: a substrate whose normal direction of a principal surface is inclined to one direction of a [1 1 1] crystal orientation relative to one direction of a [1 0 0] crystal orientation; a resonator structural body including an active layer, a lower spacer layer and an upper spacer layer, wherein the active layer is at a center of the resonator structural body, the center corresponding to an anti-node position of a standing wave distribution of an electric field, and wherein a center part of the lower spacer layer forms a base of a mesa structure; first and second semiconductor distributed Bragg reflectors which sandwich the resonator structural body and include a confinement structure in which a current passing-through region is surrounded by an oxidized layer; a plurality of semiconductor layers stacked on the substrate; and a metal layer having an opening part which becomes a light outputting section on the plural semiconductor layers, wherein a laser beam whose cross sectional shape has a long length direction is input to the metal layer via the oxide confinement structure; and an opening width of the light outputting section in a first direction orthogonal to the long length direction of the laser beam is smaller than another opening width of the light outputting section in a second direction parallel to the long length direction of the laser beam.
