Numerical Simulations of Scattering in a Two-Photon Optical Data Storage System

Abstract

Scattering effects in a two-photon optical data storage system are numerically studied. Surface scattering analysis using a scalar, beam propagation model is performed. The problem is analyzed by computing scattering from randomly varying surfaces, and also by Fourier surface decomposition. Scattering induced by propagation through pages of randomly recorded data marks is also studied using a hybrid finite difference time domain angular spectrum model. Both surface and bulk scattering are shown to influence the spatial properties of the optical beam. Results and some possible implications are presented.
