英文摘要	A semiconductor optical device has a gain region for oscillating a laser light beam and a spot-size conversion region for converting a spot-size of the laser light beam emitted from the gain region. Further, an optical waveguide (3) is formed by the use of a selective growth mask (2) along the gain region and the spot-size conversion region. With such a structure, the optical waveguide (3) includes a waveguide taper region (5) and has a width (W0) and a facet. In this event, the width (W0) gradually becomes narrower towards the facet. As a result, the waveguide taper region (5) is tapered along a direction from the gain region towards the facet.
