Abstract
A structure for electro-optic channeling of multimode light radiated from multimode fiber optic waveguides is disclosed. The light is channeled in a planar optic waveguide comprised of a high index electro-optic material to which the fiber optic waveguide is non-normal butt coupled to achieve higher in-plane collimation and greater confinement of divergent light beams with lower control voltages.
