Laminated polymer optical waveguide and process for producing the same
First Claim
1. A laminated polymer optical waveguide comprising two or more optical waveguide films each of which comprises an optical waveguide core on a light-transmissive clad film, the two or more optical waveguide films being laminated on each other by using a clad-forming curable resin having a refractive index close to that of the light-transmissive clad film, wherein the laminated polymer optical waveguide comprises, at an end thereof, a plurality of strip-shaped structures which each comprise at least one optical waveguide core and which can be each independently bent in the direction along which the optical waveguide films are laminated.

Abstract
A laminated polymer optical waveguide including two or more optical waveguide films each of which includes an optical waveguide core on a light-transmissive clad film, the two or more optical waveguide films being laminated on each other by using a clad-forming curable resin having a refractive index close to that of the light-transmissive clad film. The laminated polymer optical waveguide includes, at an end thereof, plural strip-shaped structures which each include at least one optical waveguide core and which can be each independently bent in the direction along which the optical waveguide films are laminated.
