摘要： PROBLEM TO BE SOLVED: To provide an optical waveguide circuit, having high controllability of the reflection angle and satisfactory yield of production. SOLUTION: The optical waveguide circuit comprises a first side face substantially orthogonal to an optical axis; a second side face facing the first side face substantially parallel to the same; and a third side face, arranged so as to form an internal angle with the second side face of 90° to 180°. Since the second-side face and the third-side face form the internal angle of 90° to 180°, a curable resin made to flow into a mirror groove can be prevented from swelling due to its surface tension on the third-side face. Accordingly, a reflecting part having a flat surface can be formed. Furthermore, the mirror groove can be prevented from being embedded by the curable resin. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem associated with the generation of optical cross talk through multiple reflection within a planar optical circuit, to reduce the size, and to provide a good cross talk performance. SOLUTION: A first light shielding member 26 is arranged between light receiving side reflection surfaces 25a which are provided in the path from incident light beams to a light receiving section and optical circuit side reflection surfaces 22a, which are the top surface of a planar optical circuit 22 and the rear surface like of a substrate 21, with a distance from the light receiving section side reflection surfaces 25a. A second light shielding member 27 is arranged in the region, which is sandwiched between the light receiving side reflection surfaces 25a and the first light shielding member 26, so as to optically shield the set of mutually different light emitting sections and light receiving sections 25. Thus, reflected optical components having angles which are equal to or greater than the angles determined by the distance between the light receiving section side reflection surfaces 25a and the light shielding film and by the opening width of the light shielding film, can not reenter onto the planar optical circuit, and no major cross talk is generated even though mirror light emitting angles are greatly dispersed.

摘要： PROBLEM TO BE SOLVED: To solve a problem in which a manufacturing yield is lowered through angular deviation of a 45° tilted mirror, in a vertical optical path conversion mirror circuit that makes light exit and enter from the optical waveguide of a planar optical circuit. SOLUTION: A mirror protection plate installed for protecting the vertical optical path conversion mirror is designed so that the exiting surface of the plate has a prescribed inclination to the planar circuit. Consequently, correction of the angular deviation of the mirror is made possible, which can realize the vertical optical path conversion mirror having high accuracy in the outgoing angle. Forming a tilted groove makes simple angular correction possible using conventional manufacturing equipment. Also, the angular correcting plate can realize angular correction that is simple and excellent in workability. COPYRIGHT: (C)2006,JPO&NCIPI
