title: Polarization-assisted transverse and axial optical superresolution.
abstract: The superposition of two coaxial Gaussian beams with offset foci and orthogonal linear polarizations can be used to produce a right- or leftcircular polarization component with a focal spot of volume smaller than that of the Gaussian beam. This polarization-assisted axial and transverse superresolution effect is attributed to the differential Gouy phase shift within the focal region or to the non-Gaussian annular distribution of the circularlypolarized components in the far field.
