METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE DEVICE, OPTICAL WAVEGUIDE DEVICE, AND OPTICAL WAVEGUIDE CONNECTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical waveguide device with high productivity, an optical waveguide device, and an optical waveguide connector.SOLUTION: The method for manufacturing an optical waveguide device comprises the steps of: forming a photocurable heat-foaming resin layer on a light-transmitting substrate; laminating an optical waveguide film having a plurality of optical waveguides arranged into a row in a lateral direction on the heat-foaming resin layer; curing the heat-foaming resin layer by irradiating the heat-foaming resin layer through the light-transmitting substrate with light in an irradiation quantity which differs by each region segmented along the plurality of optical waveguides; forming a gap in the heat-foaming resin layer and the optical waveguide film to separate the regions from one another; and heating and foaming the heat-foaming resin layer.
