Abstract
The present invention is a three-dimensional tapered waveguide coupler capable of interconnecting electro-optical devices with differing optical mode profiles. The ends of the waveguide are configured to match the optical mode profiles of the electro-optical devices that the waveguide interconnects. The waveguide adiabatically transmits the fundamental mode of the photo-optic signal from the electro-optical device at the waveguide's input end to a different electro-optical device at the waveguide's output end. A single coupler can be configured with one or more waveguides, each waveguide having different optical mode profiles at either end and different optical transmission characteristics.
