  • Abstract
    This paper investigates the in-line differential push-pull signal simulation for the Blu-ray disk system using the scalar diffraction theory. A simple calculation scheme was proposed. With the simulation flow, six different types of in-line gratings were analyzed, compared, and discussed. The simulation results show that the pattern with three segmented central regions has the best signal performance.
