ABSTRACT:
One or more first portions of a reduced optical material wafer are covered with a masking layer that leaves uncovered one or more second portions of the reduced optical material wafer. The reduced optical material wafer is exposed to an oxidizing atmosphere to reverse a reduction of the one or more second portions of the reduced optical material wafer that makes the one or more second portions receptive for implementation of one or more optical waveguides.
