摘要： PROBLEM TO BE SOLVED: To obtain an optical deflector of a waveguide type which is uniform in light intensity characteristics on a scanning plane. SOLUTION: This optical deflector is constituted by laminating an optical waveguide layer 2 on a substrate 1 and providing the front surface of this optical waveguide layer 2 with incident gratings 5, exit gratings 6 and an IDT 7 for exciting surface acoustic waves. The optical deflector described above uniformly corrects the light intensity at the scanning surface of exit light by modulating the power of a power source 11 of a light source unit 10 for radiating a laser beam and the power of a high-frequency power source 8 of the IDT 7.

摘要： PROBLEM TO BE SOLVED: To provide the easily manufacturable optical waveguide input/ output device of high light incidence/emission efficiency and a simple structure provided with a grating coupler. SOLUTION: This device 1 is constituted of a substrate 2, an optical buffer layer 3, an optical waveguide layer 4 and the grating coupler 10 for incidence, etc. The thickness of the optical buffer layer 3 is set so as to match the phases of substrate side emitted light L2 and the waveguide light L1 of incident light L at a position B. The light L made incident on the grating coupler 10 is diffracted and separated into the waveguide light L1 and the substrate side emitted light L2. The substrate side emitted light L2 is reflected at the boundary of the substrate 2 and the optical-buffer layer 3 and made incident on the grating coupler 10 again. The substrate side emitted light L2 is diffracted again by the grating coupler 10 and turned to the waveguide light. At the time, the substrate side emitted light L2 and the waveguide light L1 of the incident light L are optically coupled in the state of intensifying each other.
