TLDR
It is shown that focal spot shape is highly sensitive to both polarization and angular spectrum of the incoming light and a lateral spatial resolution of 145 nm (lambda(0)/9) in the direction perpendicular to the polarization direction is demonstrated.
Abstract
We investigate the effect of an annular pupil-plane aperture in confocal imaging while using an NA increasing lens. We show that focal spot shape is highly sensitive to both polarization and angular spectrum of the incoming light. We demonstrate a lateral spatial resolution of 145 nm (λ0/9) in the direction perpendicular to the polarization direction.

Enhanced resolution beyond the Abbe diffraction limit with wavelength-scale solid immersion lenses

TL;DR: From full three-dimensional, finite-difference time-domain calculations, it is demonstrated that the FWHM of the focal spot of an objective-lens-nSIL system can be reduced by greater than 25% compared to a regular macroscopic SIL.

Orientational imaging of single molecules by annular illumination

TL;DR: The absorption dipole orientation of single fluorescent molecules is determined by mapping the spatial distribution of the squared electric field components in a high-numerical-aperture laser focus and holds promise to monitor rotational diffusion of single molecules in complex environments.
