ABSTRACT:
Coupling among discrete propagation modes of light energy is achieved by providing perturbations of finite length in an optical waveguide. An optimal function characterizing the perturbation is disclosed along with a method of implementing the function to obtain uniform coupling strength over a desired range of modes.
