Abstract:
1. An optical element comprising: a surface-emitting type semiconductor laser includes a substrate, a first mirror, an active layer, and a second mirror having a current constricting layer arranged from the side of the substrate; a light-receiving element that detects a part of laser light emitted from the surface-emitting type semiconductor laser; and an isolation layer between the surface-emitting type semiconductor laser and the light-receiving element for electrically isolating the surface-emitting type semiconductor laser from the light-receiving element, the isolation layer directly contacting the second mirror, wherein the isolation layer has a plane configuration that has anisotropy, an opening section defined by the current constricting layer has a plane configuration that has anisotropy, and the light-receiving element is formed above the surface-emitting type semiconductor laser and includes a semiconductor layer having one or more layers, and at least one of the layers in the semiconductor layer has a plane configuration that has anisotropy.
