Abstract

Coupling characteristics between two curved dielectric waveguides that lie in a plane and have the same center of curvature are discussed. Analysis is carried out by using the coupled-mode equations. It is found that (i) the maximum power transfer efficiency between two curved waveguides having the same propagation constant changes from 0 to 1 as the radius of curvature increases and (ii) complete power transfer between two waveguides having different propagation constants can be realized by bending the two guides with suitable radii of curvature.
