  • Semiconductor laser element and near-field light output device using same
    Patent number: 9614350
    Abstract: A semiconductor laser element is provided with: a substrate formed of a semiconductor; a semiconductor laminated film, which is laminated on the substrate, and which includes an active layer; a first electrode and a second electrode, which are provided on surfaces parallel to the active layer on the side where the semiconductor laminated film is formed on the substrate; and a facet protection film that is provided on both the facets, which are perpendicular to the active layer, and which face each other. In the semiconductor laser element, the facet is used as a fixing surface for the semiconductor laser element, said facet having the facet protection film formed thereon.
    Type: Grant
