Abstract
We report the first demonstration of channel optical waveguide directional couplers. The closely spaced channel waveguides were fabricated in GaAs by proton implantation. Optical coupling was observed at 1.15 µ with complete light transfer out of the initial channel into adjacent channels in lengths of typically 2 mm.
