dc.description.abstract | In this paper, we employed full vector diffraction treatment to study the dependence of the servo signals to the doughnutshaped focus radiation of radial polarization, which provides a smaller spot size than linear polarization, and the resistance to the primary aberrations in a numerical aperture (NA) = 1.0 optical data storage system. Compared with linear polarization, at strong focusing, a radially polarized beam leads to 14% asymmetry reduction in the linear range of the focus-error signal (FES) curve and to at least 56% variation reduction in crosstalk in a weakly aberrated system. These characteristics make radial polarization a potential candidate for next-generation high-density optical systems. | en_US |
