Surface Emitting Shg Light By Counter Propagation Of Guided Waves In A Plane Parallel Poled Dans Side Chain Polymer

Abstract

Large nonlinear optical coefficients and easy processing and fabrication techniques make organic materials, especially polymers, very attractive condidates for counter propagating mixing applications. Here a spincoated waveguide based on a 4‐dimethylamino‐4\u27‐nitrostilbene side chain polymer is shown to generate surface emitted second harmonic light. The preparation of the waveguide, its experimental operation, and the theoretical background are discussed. Copyright © 1995 Verlag GmbH & Co. KGaA, Weinhei
