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
