Abstract
We demonstrate second‐harmonic generation due to counterpropagating beams in planar waveguides of 2‐docosylamino‐5‐nitropyridine (DCANP). The DCANP molecules were deposited by Langmuir–Blodgett techniques and have a preferred alignment within the substrate plane. Four‐layer waveguide structures were used to optimize the trade‐off between propagation loss and efficient surface‐emitted green light.Keywords
