FABRICATION OF POLYMER WAVEGUIDE USING UV-MOLDING METHOD

摘要

The present invention relates to a method of producing a polymeric optical waveguide using a UV molding method , the lower cladding layer over the coated substrate , and then the waveguide pattern is formed in the negative mold and the substrate pattern is facing that position , and the photo-curing polymer resin injected to the mold to form a core layer , and then photo-cured by removing the mold , the negative of the waveguide patterns are arranged in parallel to the plurality of waveguide pattern , the pattern ends of the neighboring waveguides are connected to each other by more than one band , and the photo-curing polymer resin is injected through one end of the band portion , the method of the present invention According to , a multi-mode optical waveguide to the core around which does not have a lip (lip) can be easily produced .
