摘要 |
A semiconductor optical waveguide-A having an optical amplification function and a semiconductor optical waveguide-B having a light control function are integrated together on the same substrate. A facet of the semiconductor optical waveguide-A facing an isolation trench and a facet of the semiconductor optical waveguide-B facing the isolation trench are configured as a composite optical reflector/optical connector using an optical interference. The facet of the semiconductor optical waveguide-A achieves an optical reflectivity not higher than the reflectivity corresponding to a cleaved facet and not smaller than several percent, and an optical coupling coefficient of not lower than 50% between the semiconductor optical waveguide-A and the semiconductor optical waveguide-B.
