Abstract
An integrated optical device including: a silicon substrate (1 ); an optical waveguiding core (4 ) formed on the silicon substrate (1); a clad layer formed encircling the optical waveguiding core (4): an optical fiber groove (5) having a V-character shaped cross section for position-aligning an optical fiber so as to optically couple the optical waveguiding core and the optical fiber, the optical fiber groove being formed on the surface of the silicon substrate along an optical axis in one direction from one end plane of the optical waveguiding core; an edge input/output type optical semiconductor device (8) having an active region bonded to the clad layer, the optical semiconductor device being mounted on a line extending from the other end plane of the optical waveguiding core along the optical axis; and an optical axis level changing member (10, 11, 12) for optically coupling the optical waveguiding core and the optical semiconductor device by changing the heights of optical axes relative to the surface of the silicon substrate at both the optical semiconductor device and the optical waveguiding core.
