Abstract
The waveguide multilayer optical memory is a novel and promising subject in the optical storage field compared with other 3D optical memory techniques. To our certain knowledge, how to establish the information scattering model of the single-layer waveguide optical memory is not found. In this paper, the Lippman-Schwinger equation and dyadic Green's function are used to compute an exact solution of the wave equation about the single-layer plane waveguide with information recorded. Then, the constructing method of the dyadic green function of the perfect plane waveguide with three layered structures is presented. Among the numerical calculations, a method about double integration of rapidly oscillatory function is introduced in detail. Based on the above method, the information scattering model of the waveguide single-layer optical memory will be constructed. According this theoretic model, with the computer simulation, the scattered light intensity distribution on the detector plane is showed. The scattering light intensity of the single information pit that is on behalf of information is also given.
