Polarization States in Near-Field Optical Recording System using a Solid Immersion Lens Illuminated by a Coherent Polarized Light

Absrracr-We use n vector diffraction model of coherent 11. GENERALIZED DIFFRACTION INTEGRALS light focused hy an optical near-field system, fnr extracting the polarization information and its alteratinn when experiencing a AS pointed by T6r6k et al. [S], in focusing systems with phase change optical disk structure. large Fresnel numbers (focal distance many wavelengths away from the aperture) the electric field inside medium j can be written as a coherent sum of vector plane waves over the exit
