title = "Polarization-dependent optical responses of Sb-type near-field optical disk structure",
abstract = "The near-field and far-field optical properties of Sb-type near-field optical disk structures with different polarized situations are studied by finite-difference time-domain (FDTD) method. Localized surface plasmon enhancements are found around rough surface of Sb layers for TM polarized, but no near-field enhancement is found in cases with TE polarized incident waves. Far-field readout contrast signals of both TE and TM polarized situations show the super-resolution capability, because evanescent signals of subwavelength recording marks are coupled to propagating waves by nanostrucrures (nano aperture or rough surface) in near-field active layer. Nevertheless, the contrast signals for TM illumination are higher than TE illumination due to localized surface plasmon enhancements. A simplified Fourier optics model is used to describe the relation between highly localized near-field distributions and enhanced resolution of far-field signals.",
