We review optical phenomena associated with the internal energy redistribution which
accompany propagation and transformations of monochromatic light fields in homogeneous …

Cylindrical-vector beams are of increasing recent interest for their role in novel laser
resonators and their applications to electron acceleration and scanning microscopy. In this …

In the search for higher resolution, modern day imaging systems frequently employ objective
lenses with a high numerical aperture. Propagation of light through such lenses introduces a …

We present a general theory of spin-to-orbital angular momentum (AM) conversion of light in
focusing, scattering, and imaging optical systems. Our theory employs universal geometric …

We show, both theoretically and experimentally, that high-numerical-aperture (NA) optical
microscopy is accompanied by strong spin-orbit interaction of light, which translates fine …

This paper examines the use of Gauss-Laguerre beams in STED microscopy. These types of
beams are shown to have beneficial properties that can be utilised to generate stable, high …

We examine, both experimentally and theoretically, an interaction of tightly focused
polarized light with a slit on a metal surface supporting plasmon-polariton modes …

In this paper we present a rigorous and general theoretical model for the illumination point
spread function of a confocal microscope that correctly reproduces the optical setup. The …

A theory is presented together with simulation results that describe three-dimensional
position detection of a sphere located in a highly focused beam by back-focal plane …

To understand polarization effects in image formation for critical structures, a model based
on the pupil approach and the Fourier modal method is presented for numerical simulation …
