Abstract: An edge emitting laser light source and a three-dimensional (3D) image obtaining apparatus including the edge emitting laser light source are provided. The edge emitting laser light source includes a substrate; an active layer disposed on the substrate; a wavelength selection section comprising grating regions configured to select wavelengths of light emitted from the active layer; and a gain section configured to resonate the light having the selected wavelengths in a direction parallel with the active layer.

Abstract: Provided are a transmission type high-absorption optical modulator and a method of manufacturing the transmission type high-absorption optical modulator. The optical modulator includes: a substrate; a lower distributed Bragg reflector (DBR) layer on the substrate; a lower clad layer on the lower DBR layer; an active layer that is formed on the lower clad layer and includes a quantum well layer and a quantum barrier layer; an upper clad layer on the active layer; an upper DBR layer on the upper clad layer; and a doping layer that supplies carriers to the quantum well layer. In the optical modulator, the doping layer may be included in the quantum barrier layer or in at least one of the upper and lower clad layers.
