摘要:
Disclosed is a surface emitting laser device, including a substrate; a lower reflecting mirror provided on the substrate; an active layer provided on the lower reflecting mirror; an upper reflecting mirror provided on the active layer, including an emitting region, laser light being emitted from the emitting region, the upper reflecting mirror being formed by alternately laminating dielectrics, refracting indices of the dielectrics being different from each other; and an adjusting layer formed of semiconductor, provided in the emitting region between the active layer and the upper reflecting mirror, a shape of the adjusting layer in a plane parallel to a surface of the substrate including shape anisotropy in two mutually perpendicular directions.
