Abstract:
1. A surface-emitting laser device comprising: a lower reflector, a resonator structure having an active layer and an upper reflector layered on an inclined substrate; and an emission region enclosed by an electrode, the emission region being configured to emit laser light, wherein the upper reflector includes a confinement structure having a current passing region enclosed by an oxide, the oxide containing at least an oxide generated as a result of partial oxidation of a layer containing aluminum subject to selective oxidation, and a dielectric film formed within the emission region, the dielectric film at least enclosing a partial region including a center of the emission region, and wherein in viewing from a direction orthogonal to the emission region, a center of a region enclosed by the dielectric film is located at a position distant from the center of the emission region based on a size of the confinement structure relative to a direction orthogonal to an inclined axis of the inclined substrate.
