Direct Detection of Circularly Polarized Light Using Chiral Copper Chloride–Carbon Nanotube Heterostructures

open access: yesACS Nano, 2021
The emergent properties of chiral organic–inorganic hybrid materials offer opportunities in spin-dependent optoelectronic devices. One of the most promising applications where spin, charge, and light are strongly coupled is circularly polarized light ...

A minimal subwavelength focal spot for the energy flux

open access: yesКомпьютерная 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.

Circular polarization of transmitted light by sapphirinidae copepods. [PDF]

open access: yesPLoS ONE, 2014
Circularly polarized light, rare in the animal kingdom, has thus far been documented in only a handful of animals. Using a rotating circular polarization (CP) analyzer we detected CP in linearly polarized light transmitted through epipelagic free living ...

Differential absorption of circularly polarized light by a centrosymmetric crystal.

open access: yesScience
Crystalline solids are governed by universal structure-property relationships derived from their crystal symmetry, leading to paradigmatic rules on what properties they can and cannot exhibit.
