ABSTRACT:
A metehod of manufacturing planar optical waveguides in which a planar optical preform which is stretched to form a planar optical cane with substantially smaller cross-sectional dimensions than the original preform, and in which the optical circuitry pattern is achieved by lithographic techniques. Optical fiber preforms may be inserted in slots in a substrate to form the planar optical preform.
