OPTICAL WAVEGUIDE AND METHOD FOR MANUFACTURING SAME

摘要

A low-cost optical waveguide wherein the use efficiency of a core material is high and a method for manufacturing such an optical waveguide are disclosed. The method for manufacturing the optical waveguide comprises a step wherein a first cladding (2) is formed by applying and curing a resin on a substrate (20), a step wherein a core material (1') is fed between a cavity mold (10) with a recess having the shape of a core pattern and the first cladding on the substrate, a step wherein a core pattern (1) corresponding to the recess is formed on the first cladding by curing the core material, and a step wherein the cavity mold (10) is removed from the core pattern and the first cladding.
