摘要: A semiconductor laser includes an active layer formed on a substrate and pair of cladding layers sandwiching the layer. On at least one resonator end faces laser, first dielectric film with hydrogen added therein is provided. Between face, second for suppressing diffusion Even when face coating including hydrogen-added exposed to high temperatures, peeling deterioration can be suppressed.
