摘要： The present invention provides a semiconductor light emitting device realizing increased light detection precision by a simple manufacture process. One or more second oxidation layers are provided between an active layer and a semiconductor light detecting element in addition to a first oxidation layer for narrowing current. Since natural emission light includes many divergence components, the natural emission light is reflected and scattered by the second oxidation layer, and propagation of the natural emission light to the semiconductor light detecting element side is suppressed. The detection level of the natural emission light by the semiconductor light detecting element decreases, and light detection precision increases. The first and second oxidation layers are formed by a single oxidizing process so that the manufacturing process is simplified.

摘要： The present invention provides a Vertical Cavity Surface Emitting Laser including: a first multilayer film reflector; an active layer having a light emission region; a second multilayer film reflector; and a reflectance adjustment layer in this order on a substrate side. The first multilayer film reflector and the second multilayer film reflector have a laminated structure in which reflectance of oscillation wavelength λx is almost constant without depending on temperature change. The active layer is made of a material with which a maximum gain is obtained at temperature higher than ambient temperature. The reflectance adjustment layer has a laminated structure in which difference ΔR(=Rx−Ry) between reflectance Rx of a region opposed to a central region of the light emission region and reflectance Ry of a region opposed to an outer edge region of the light emission region is increased associated with temperature increase from ambient temperature to high temperature.
