Magnetized current filaments as a source of circularly polarized light [PDF]
Journal of Plasma Physics, 2021 We show that the Weibel or current filamentation instability can lead to the emission of circularly polarized radiation. Using particle-in-cell simulations and a radiation post-processing numerical algorithm, we demonstrate that the level of circular polarization increases with the initial plasma magnetization, saturating at ${\sim }13\,\%

Spin detector for panchromatic circularly polarized light detection. [PDF]
Nat CommunCircularly polarized light (CPL) detection is crucial for optical communication, bioimaging and quantum computing. However, CPL detectors based on chiral low-dimensional perovskites face a trade-off between optoelectronic performance and CPL discrimination, and typically exhibit a CPL response within a narrow spectral range.

Circularly Polarized Light as a Communication Signal in Mantis Shrimps [PDF]
Current Biology, 2015 Animals that communicate using conspicuous body patterns face a trade-off between desired detection by intended receivers and undesired detection from eavesdropping predators, prey, rivals, or parasites. In some cases, this trade-off favors the evolution of signals that are both hidden from predators and visible to conspecifics.

Depolarization composition of backscattered circularly polarized light
Physical Review A, 2023 We consider the origin of unpolarised light resulting from the backscattering of circularly polarized light by random turbid tissue-like disperse medium. We reveal the dynamics of the backscattered fraction of unpolarized light, disclosing its meticulous decomposition into two rigorously polarized components characterized by opposing helicities, with ...

Nanophotonics, 2022 The spin Hall effect of light (SHEL) is the microscopic spin-dependent splitting of light at an optical interface. Whereas the spin Hall shift under linearly polarized light is well-formulated, studies on the SHEL under elliptically or circularly ...

Recollisions and Correlated Double Ionization with Circularly Polarized Light [PDF]
Physical Review Letters, 2010 It is generally believed that the recollision mechanism of atomic nonsequential double ionization is suppressed in circularly polarized laser fields because the returning electron is unlikely to encounter the core. On the contrary, we find that recollision can and does significantly enhance double ionization, even to the extent of forming a "knee", the

All-Optical Magnetic Recording with Circularly Polarized Light [PDF]
Physical Review Letters, 2007 We experimentally demonstrate that the magnetization can be reversed in a reproducible manner by a single 40 femtosecond circularly polarized laser pulse, without any applied magnetic field. This optically induced ultrafast magnetization reversal previously believed impossible is the combined result of femtosecond laser heating of the magnetic system ...

Comparison of backward flow values in the sharp focus of light fields with polarization and phase singularity [PDF]
Компьютерная оптика, 2019 Using Jones matrices and vectors, we show that an optical metasurface composed of a set of subwavelength binary diffraction gratings and characterized by an anisotropic transmittance described by a polarization rotation matrix by the angle mφ, where φ is

A minimal subwavelength focal spot for the energy flux
Компьютерная оптика, 2021 It is shown theoretically and numerically that circularly and linearly polarized incident beams produce at the tight focus identical circularly symmetric distributions of an on-axis energy flux.
