Polarization of light and topological phases
TLDR
In this article, a survey and analysis of recent work on topological phases with polarization of light is presented, which has revealed several counterintuitive features of such phase shifts such as 2 nπ anholonomies, nonlinear and discontinuous behaviour originating from high singularities, peculiar spectral dependence, etc.About:

Optical spin-to-orbital angular momentum conversion in inhomogeneous anisotropic media
TL;DR: An optical process in which the spin angular momentum carried by a circularly polarized light beam is converted into orbital angular momentum, leading to the generation of helical modes with a wave-front helicity controlled by the input polarization is demonstrated.
Journal ArticleDOI
Spin-orbit interactions of light
TL;DR: In this paper, the authors provide an overview of the fundamental origins and important applications of the main spin-orbit interaction phenomena in modern optics that play a crucial role at subwavelength scales, including spin-Hall effects in inhomogeneous media and at optical interfaces, spindependent effects in non-paraxial (focused or scattered) fields, spin-controlled shaping of light using anisotropic structured interfaces (metasurfaces).

Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface
Ebrahim Karimi,Sebastian A. Schulz,Israel De Leon,Hammam Qassim,Jeremy Upham,Robert W. Boyd,Robert W. Boyd +6 more
TL;DR: Karimi et al. as mentioned in this paper showed that a plasmonic metasurface comprising an array of nano-antennas can couple spin-to-orbital angular momentum at thickness much smaller than the wavelength of the light with an efficiency of around 3%.

Geometry of self-propulsion at low Reynolds number
Alfred D. Shapere,Frank Wilczek +1 more
TL;DR: In this article, the problem of swimming at low Reynolds number is formulated in terms of a gauge field on the space of shapes, and effective methods for computing this field, by solving a linear boundary-value problem, are described.

Optical Signal Processing
TL;DR: In this paper, a decimated array is used to detect and track frequency hopped radio signals in a dense electromagnetic environment by using cross-spectrum of two signals obtained from antenna elements spaced by one-half an RF wavelength.

A New Calculus for the Treatment of Optical SystemsIII. The Sohncke Theory of Optical Activity
TL;DR: In this article, the authors examined the properties of a rotational retardation system with a large number of identical retardation plates, each of which is rotated with respect to the one preceding it through the angle ω.

A universal compensator for polarization changes induced by birefringence on a retracing beam
TL;DR: In this paper, a new optical scheme that eliminates birefringence effects on the polarization state of a beam which retraces its path was proposed. But it does not control the exit polarization state but it removes the bireringence change effect at its source.
