Abstract

A three-dimensional combined vectorial method, which is based on the finite-difference time-domain algorithm and vectorial diffraction formulation, is introduced to analyze the interaction of a realistic focused beam with a metallic grating in an optical storage system. The diffracted field patterns and the detected signals are calculated for gratings with different geometries, and the polarization-dependent characteristics are studied. The combined method can give accurately the detected signals and the field pattern at any desired position of the optical storage system.
