Bended interconnection using Graded Index optical waveguide for high speed optical communication

The interchip information transmission by the optical signal is promising in the band of 10 GHz or more in the future. Since high speed transmissions are more possible than alignment easiness and the multimode waveguides by making of the core diameter a large diameter, we proposes the use of the GI (Graded-Index) waveguide that has the curved structure without the reflection mirror. In this study, it was clarified that the power loss was small regardless of a small curvature. A periodic loss related to the length of the straight line part of the waveguide was found in the analysis by using the ray tracing method. The correction curve and the elliptic curve were proposed as the solution of the problem.
