ABSTRACT:
A semiconductor laser device with a spot-size converter includes at least a semiconductor laser region emitting light from an end facet thereof and a light waveguide region. The semiconductor laser region and the light waveguide region are integrated on a semiconductor substrate in a horizontal direction. A semiconductor layer is buried in a junction region between the semiconductor laser region and the light waveguide region.
