IPC: G02F1/01
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To increase the intensity of monitor light while adjusting the projection position of interference light as monitor light on a projection-side end surface by generating the interference light by making light exiting from a light guide part and signal light leaking from an optical waveguide part interfere with each other. SOLUTION: Light emitted from a Y-shaped multiplexing part R2 and part of the signal light leaking from the Y-shaped multiplexing part R2 are made incident on a light guide area 21 provided nearby the optical waveguide part 3. The light guide area 1 guides the light emitted from the Y-shaped multiplexing part R2 and the leaking signal light so that they will not exit from end surfaces of a substrate 1a except the projection-side end surface. Namely, the incident light is prevented from being scattered to increase the intensity of monitor light projected from the projection end surface of the substrate 1a. Then the light projected from the light guide area 21 (principally the emitted light) further interferes with the signal light leaking from the Y- shaped multiplexing part R2 when propagated in the substrate 1a and is projected from the projection-side end surface of the substrate 1a as monitor light (interference light).
