Abstract

Techniques and devices are disclosed to provide controlled inter-mode cross-talk in multimode optical waveguides. The structure of a bent multimode optical waveguide can be designed or configured in a way that either substantially minimizes inter-mode cross talk or achieves a desired inter-mode cross-talk. Specific examples based on the disclosed waveguide designs are provided for semiconductor integrated waveguide devices.
