Abstract
A semiconductor light source includes a substrate, an optical waveguide having a reflection structure provided on the substrate with an oxide film in between and a semiconductor light emitting element provided on the optical waveguide. The optical waveguide includes a constant width core layer portion located in a center portion, tapered core layer portions that are provided on either side of the constant width core layer and of which the core width gradually increases and a constant width core layer portion for an optical wire waveguide. The semiconductor light emitting element is placed so as to cover at least a portion of the tapered core layer portions on both sides.
