摘要： A surface emitting laser array includes a light emitting unit having a lower reflection mirror, a resonator structure including an active layer, and an upper reflection mirror laminated on a substrate; an electrode for the light emitting unit; a wiring member that establishes electrical connection between the light emitting unit and the electrode; and the substrate on which more than one of the light emitting units, the electrodes, and the wiring members are arranged. The light emitting unit has anisotropic internal stress, and the distance between the center of a first light emitting unit and the center line of the corresponding wiring member is arranged to be different from the distance between the center of a second light emitting unit and the center line of the corresponding wiring member so that variations in the polarization directions of the light emitting units may be within a predetermined range.

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.
