Title:
SURFACE-EMITTING LASER, SURFACE-EMITTING LASER ARRAY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/181716
Kind Code:
A1
Abstract:
Provided are a surface-emitting laser, a surface-emitting laser array, and an electronic device in which the reliability of a transparent conductive film is increased. The present technology provides a surface-emitting laser in which a first structure that includes a first multilayer reflector, an active layer, and a second structure that includes a transparent conductive film, a pad electrode, and a second multilayer reflector are disposed in this order. The film thickness of the transparent conductive film disposed in a position in contact with the pad electrode is greater than the film thickness of the transparent conductive film disposed on an optical path of light generated by the active layer.
