This invention provides process embodiments for fabrication of organic optical waveguides. A preferred invention optical waveguide consists of a thin film matrix of three electrodes, one of which has a spatial periodic structure, and a side chain polymeric waveguiding medium positioned between two side chain polymeric cladding layers. The electrodes are adapted to apply electric fields of opposite polarity and to pole the polymer side chains bidirectionally in a noncentrosymmetric orientation of periodic reverse polarity. The waveguiding medium and cladding thin films exhibit second order nonlinear optical susceptibility χ.sup.(2), and are adapted to phase-match propagating radiation waves. |
