Abstract
This invention provides polymeric chanel waveguides which are formed by means of an excimer laser photoablation procedure. The smooth-wall channel waveguides polymeric medium is in combination with polymeric cladding layers to form a laminated matrix. The polymers in the waveguiding medium and the cladding layers of the laminated matrix have side chains which exhibit second order nonlinear optical susceptibility, and which can be molecularly oriented by an electric field.
