Patent ID: 8855159

Claim:
A surface-emitting laser element comprising: a resonator structure having an active layer; a first semiconductor multilayer mirror and a second semiconductor multilayer mirror configured to sandwich the resonator structure having the active layer; an electrode provided around an emission region of a light-emitting surface; and a first dielectric film provided in a peripheral portion within the emission region and outside a central portion of the emission region to make a reflectance of the peripheral portion lower than a reflectance of the central portion, wherein an external shape of the emission region corresponds to an internal shape of the electrode, wherein the first dielectric film provided in the peripheral portion of the emission region has shape anisotropy in two orthogonal directions, and wherein when viewing from a laser oscillation direction, an outer shape of a portion where the electrode provided around the emission region of the light-emitting surface is in contact with a contact layer includes corners, and an inner shape of the portion where said electrode provided around the emission region of the light-emitting surface is in contact with the contact layer includes a curve.
