Abstract
An optical interconnect for coupling a collimated free space light beam to a raised channel waveguide formed on a substrate. A modified graded index rod lens has a flattened polished surface parallel to its optical axis. The rod lens is positioned with the flattened surface adjacent the substrate and an endface spaced from the waveguide endface so that a collimated light beam entering the lens will be focused onto the waveguide endface.
