| 英文摘要 | A surface-emitting laser device includes a lower reflector, a resonator structure having an active layer and an upper reflector on an inclined substrate, and an emission region emitting laser light enclosed by an electrode. The upper reflector includes a confinement structure having a current passing region enclosed by an 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. 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. |
