ABSTRACT:
A method of producing a substrate for an optical surface mount circuit including the steps of forming an optical wave guide in the substrate, wherein the optical wave guide has a zone of refraction gradient decreasing from a central axis thereof toward surrounding portions thereof, and end surfaces of the optical wave guide are exposed to the front surface of the substrate. Portions of the substrate are masked and salts of metallic cations are contacted to the substrate to form the optical wave guide and the end surfaces thereof.
