OPTICAL WAVEGUIDE ARRAY SUBSTRATE, OPTICAL WAVEGUIDE TYPE IMAGE SENSOR, AND METHOD FOR COUPLING OPTICAL WAVEGUIDE ARRAY SUBSTRATE TO PHOTOELECTRIC CONVERTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an optical waveguide array substrate by which the optical waveguide pitch of the output end surface of the optical waveguide array substrate can be easily adjusted, and to provide an optical waveguide type image sensor and a method for coupling the optical waveguide type image sensor to optical waveguide array. ;SOLUTION: This optical waveguide array substrate 2 which is constituted by arraying optical waveguides 1 inside and guiding an input image made incident from an input part to the optical waveguides 1, and reduces and projects the image from an output part gradually varies in the pitch of the optical waveguides 1 nearby the output part and makes it possible to adjust the optical waveguide pitch of the output end surface according to a cutting position.;COPYRIGHT: (C)1999,JPO
