Abstract
Recently we have analyzed light transmission and spectral selectivity by optical channels in Müller cells and other transparent cells, proposing a model of their structure, formed by specialized intermediate filaments [1,2]. Our model represents each optical channel by an axially symmetric tube with conductive walls. Presently, we analyze the planar polarization selectivity in long nanostructures, using the previously developed approach extended to structures of the elliptic cross-section. We find that the output light polarization degree depends on the a/b ratio, with a and b the semiaxes of the ellipse. Experimental tests used a Cr nano-strip device to evaluate the transmitted light polarization. The model adapted to the experimental geometry provided an accurate fit of the experimental results.
Highlights
The celestial distribution of the angle of the skylight polarization, being the same under all possible sky conditions, is used for the orientation by polarization-sensitive animals, including many vertebrates [3]
We developed a quantum mechanism (QM) of the electromagnetic field (EMF) transmission by a waveguide [1,2], a capillary with conductive walls, with the diameter significantly smaller than the EMF wavelength
We extend the earlier developed modeling approaches describing light transmission by intermediate filaments, present, for example, in the Müller cells
Summary
The celestial distribution of the angle of the skylight polarization, being the same under all possible sky conditions (clear, fog, clouds, etc), is used for the orientation by polarization-sensitive animals, including many vertebrates [3]. The first spectroscopic measurements found rhodopsin dipoles in the vertebrate photoreceptors free to rotate within the photoreceptor membrane without any preferred orientation to the incident light, rejecting the possibility for their polarization sensitivity [5,6]. These earlier results have been criticized later. Rhodopsin mobility was significantly restricted in some species [10], explained by its possible oligomerisation [11] These data suggest that the photoreceptors may be intrinsically sensitive to polarization, at least in some vertebrate species
