    摘要： In a surface emitting laser element (100), on a substrate (101) whose normal direction of a principal surface is inclined, a resonator structural body including an active layer (105), and a lower semiconductor DBR (103) and an upper semiconductor DBR (107) sandwiching the resonator structural body are stacked. A shape of a current passing through region (108b) in an oxide confinement structure of the upper semiconductor DBR (107) is symmetrical to an axis passing through a center of the current passing through region (108b) parallel to an X axis and symmetrical to an axis passing through the center of the current passing through region (108b) parallel to a Y axis, and a length of the current passing through region (108b) is greater in the Y axis direction than in the X axis direction. A thickness of an oxidized layer (108a) surrounding the current passing through region (108b) is greater in the -Y direction than in the +X and -X directions.

    摘要： An optical device includes at least one surface emitting laser device having a dielectric film for causing a central portion of a light emitting region to have a comparatively higher reflectivity than a peripheral portion; a light receiving element disposed, with respect to a first direction, on one side to the surface emitting laser device; and a transparent member disposed in a path of light emitted from the surface emitting laser device and configured to reflect a portion of the light toward the light receiving element as monitoring light. The central portion has shape anisotropy in which a width measured on a line extending in the first direction and passing through the center of the light emitting region is smaller than a width measured on a line extending in a second direction, which is perpendicular to the first direction, and passing through the center of the light emitting region.
