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.
摘要:
Some of the embodiments of this invention provide optical waveguides which achieve high use efficiency of core material and which are inexpensive. Some other embodiments of the invention provide methods of manufacturing such optical waveguides. An method of manufacturing an optical waveguide, according to the invention, comprises a step of forming a first clad (2) by applying a resin on a substrate (20) and curing the resin, a step of applying a core material (1') between a recessed mold (10) which has a recess having a shape identical to a shape of the core, and the first clad (2) which is provided on the substrate, a step of curing the core material thus applied, thereby forming a core pattern (1) having a shape corresponding to that of the recess, and a step of peeling the recessed mold (10) from the core pattern and the first clad.
