Polarization-assisted transverse and axial optical superresolution.

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 n...

Axial superresolution with ultrahigh aperture lenses.

We explore the current limits of the axial resolution of optical sectioning microscopy using a single lens, by combining the resolving power of novel 1.45 numerical aperture oil immersion lenses with superresolving binary aperture filters. We quantify the axial resolution brought about by the increase in semiaperture angle to max á =72.8 degrees and demonstrate an absolute gain in axial resolut...

Optical superresolution and visual hyperacuity

Classically, diffraction theory sets a boundary for the resolving capacity of optical instruments. Yet some visual thresholds have values much better than the traditional resolution limit. Recent developments in superresolution, an area of optical physics and engineering with claims of transcending the stated resolution limits of optical instruments, are reviewed and their possible relevance to...

Transverse polarization distributions

The transverse polarization (or transversity) distributions ∆T q(x), introduced 20 years ago by Ralston and Soper [1] and studied in more detail in the last decade [2], are one of the three sets of leading-twist quark and antiquark distribution functions – the other two are the momentum distributions q(x) and the helicity distributions ∆q(x). (Note that ∆T q is often called h1). Formally ∆T q i...

Polarization Independent Raman-Assisted Fiber Optical Parametric Amplifiers

We propose and demonstrate a polarization independent Raman-assisted fiber optical parametric amplifier using depolarized Raman and parametric pumps. The polarization dependent gain fluctuation has been reduced from >10 dB to less than 1 dB.
