英文摘要	According to this invention, a superluminescent diode includes a current injection portion having a current injection electrode formed adjacent to a first end face, a light-absorption portion contiguous with the current injection portion; and a waveguide continuously formed to extend from the current injection portion to the light-absorption portion. The waveguide is constituted by an active layer and a member which completely buries the active layer, has a bandgap larger than that of the active layer, and is formed of a material having a small refractive index. The waveguide of the current injection portion is linearly formed to be perpendicular to the first end face. The waveguide of the light-absorption portion has an end portion for guiding reflected light in a direction different from a propagation direction of light propagating through the waveguide.
