Semiconductor laser element, light emitting device, and method for manufacturing these

Abstract

A semiconductor laser element includes a semiconductor-containing part, an electrode and at least one metal film. The semiconductor-containing part has first and second main surfaces, a light emitting end surface, a light reflecting end surface, and an optical waveguide. A distance between the first main surface and the optical waveguide is greater than a distance between the second main surface and the optical waveguide. The electrode is provided on the first main surface. The metal film is provided on the first main surface at a position spaced apart from the electrode. The metal film is in contact with a first side of an outer edge of the first main surface on a side of the light emitting end surface. The metal film is arranged at a position that does not overlap the optical waveguide in a plan view seen along a normal direction of the first main surface.
