title: Channel Optical Waveguides and Directional Couplers in GaAs-lmbedded and Ridged.
abstract: Two-channel imbedded directional couplers were fabricated with proton implantation, yielding complete light transfer in 2 mm. Ridged channel guides were fabricated by ion-micromachining epitaxial layers, and a method of directional coupling was demonstrated.
