摘要： An optical device includes a surface-emitting laser array having a plurality of light-emitting portions; a package member on which the surface-emitting laser array is disposed; and a transparent member retained on the package member and disposed on an optical path of a light beam emitted by the surface-emitting laser array. The transparent member includes an incident plane on which the light beam emitted by the surface-emitting laser array is incident. The incident plane is inclined with respect to an emitting surface of the surface-emitting laser array at a first inclination angle which is smaller than a second inclination angle at which the light emitted by one of the light-emitting portions is incident on another, most-distant one, of the light-emitting portions via reflection by the transparent member.

摘要： In a surface emitting laser element, on an inclined substrate, a resonator structural body including an active layer, and a lower semiconductor DBR and an upper semiconductor DBR sandwiching the resonator structural body are stacked. A shape of a current passing-through region in an oxide confinement structure of the upper semiconductor DBR is symmetrical to an axis passing through a center of the current passing-through region parallel to an X axis and symmetrical to an axis passing through the center of the current passing-through region parallel to a Y axis, and a thickness of an oxidized layer surrounding the current passing-through region is greater in the +Y direction than in the +X and −X directions. An opening width of a light outputting section in the X axis direction is smaller than another opening width of the light outputting section in the Y axis direction.
