ABSTRACT:
This invention provides process embodiments for fabricating polymeric channel or rib optical waveguides.
An invention optical waveguide has a channel or rib structure which has a polymer thin film smooth-wall lining on its surfaces to minimize optical loss by scattering of propagating wave energy.
The smooth-wall channel waveguide polymeric medium is in combination with polymeric cladding thin films to form a laminated matrix. The polymers in the waveguiding medium and the lining and cladding thin films of the laminated matrix preferably have side chains which exhibit second order nonlinear optical susceptibility, and which can be molecularly oriented by an electric field.
