Abstract:
1. A method of manufacturing an optical waveguide device, comprising the steps of: (a) forming an under cladding layer on the front surface of a substrate; (b) forming a first photosensitive resin layer for core formation on a surface of said under cladding layer; (c) directing a first irradiation light through openings of a photomask toward said first photosensitive resin layer to expose said first photosensitive resin layer in a predetermined pattern to the irradiation light, thereby forming an exposed portion of said first photosensitive resin layer into a core; (d) forming a second photosensitive resin layer for over cladding layer formation covering at least the side surfaces of said core, wherein said second photosensitive resin layer is selected from a non-solvent type photosensitive resin composition; (e) heating said second photosensitive resin layer to form an interface portion between said core and said second photosensitive resin layer into a mixed layer that is a mixture of a resin material for the core formation and said photosensitive resin composition; and (f) following said heating, directing a second irradiation light toward said second photosensitive resin layer to expose said second photosensitive resin layer to the irradiation light, thereby forming an exposed portion of said second photosensitive resin layer into an over cladding layer.
