PROBLEM TO BE SOLVED: To provide an optical waveguide which is easily manufactured by a reproduction method and has a structure that prevents light signal in its inside from leaking out from a core and to provide a method of manufacturing the optical waveguide. SOLUTION: A concave slot 3 for forming a core is provided on the upper surface of cladding substrate 2. And on both sides of the concave slots 3, cavities 6 are formed via flat portions 5. An ultraviolet curing transparent resign 8 is applied onto the cladding substrate 2, thereafter the transparent resign 8 is pressed by a stamper 13. At this moment, a core 4 is formed in the concave slot 3 and excessive transparent resign 8 pressed between the stamper 13 and the flat portions 5 flows into cavities 6, as a result, it is possible to make the transparent resign 8 thin in a short time. Therefore, it is possible to make the transparent resign 8 left on the flat portion 5 into thickness and width enough to prevent light in the core 4 from leaking out. COPYRIGHT: (C)2003,JPO |
