1. | Nasalski W., Pagani Y., Cross-polarization coupling of Laguerre-Gaussian beam modes at isotropic interfaces, Conference on Nanophotonics, 2006-04-03/04-05, Strasbourg (FR), DOI: 10.1117/12.663040, Vol.6195, pp.61950L, 2006 Abstract:Excitation and cancellation of higher-order elegant Hermite-Gaussian and Laguerre-Gaussian beams under normal incidence at isotropic, lossless, dielectric interfaces are analysed. It is shown that such phenomena are originated in the cross-polarization coupling between orthogonal polarization components of the beams and depend qualitatively on interrelations between beam field spatial distribution and beam polarization. For Lagueffe-Gaussian beams these interrelations associate beam orbital and spin angular momenta. Analytic description confirmed by numerical simulations is given for transmission of two types of beams: Hermite-Gaussians of linear polarization and LagueffeGaussians of circular polarization.
