ABSTRACT:
There is to provide a method of producing efficiently a custom IC optical integrated circuit with convenient connections between tile optical devices with less loss of the light and with different connection but similar configuration. The optical integrated circuit is comprised of a plurality of ridge-type active optical devices formed of a variable wavelength laser section and a light modulator and a ridge-type passive optical waveguide of a Y-branching optical waveguide for connecting between the ridge-type active optical devices with each other or for connecting the plural ridge-type active optical devices with output waveguides, and ridge sections of the ridge-type active optical device and the ridge-type passive optical waveguide are formed by the selective crystal growth.
