Abstract
A method of fabricating composite optical channel waveguides in electro-ocal polymers. An electrically conductive substrate is coated with an ultraviolet epoxy resin which is cured by subjecting the composite to an ultraviolet light. Another layer of ultraviolet epoxy resin is applied and developed into a predetermined waveguide configuration by selective curing. The uncured epoxy is removed with a solvent which does not effect the cured ultraviolet epoxy resin. A non-linear polymer is coated over the composite and a gold electrode is deposited on its upper surface for poling purposes. After poling, the gold electrode is removed and an upper cladding is applied along with the device electrode. The invention also provides a novel waveguide as produced by the method. Where a simple waveguide is desired, the steps of applying the gold film, poling, heating, and acid etching the gold film may be omitted.
