A nonlinear dye-doped polymer optical rectification detector has an optical input for receiving a modulated optical carrier signal, an optical structure for conveying the modulated optical carrier through the detector, and an electrical structure overlaid with the optical structure arranged to optimize matching between electrical and optical waves and to enhance the second order nonlinearity of polymer in the detector. A planar waveguide fabrication method deposits a thin dye-doped polymer film onto a substrate, photobleaches one or more waveguides into the thin dye-doped polymer film, anneals the one or more waveguides to relieve stresses induced during the photobleaching process, and then forms endfaces by cleaving the substrate.
