A waveguide polarization toolset design based on mode beating [PDF]

open access: yes, 2011
A toolset of waveguide elements is examined, which can be combined to produce polarization functional devices in a single contiguous waveguide. In particular, waveguide implementations of an optical isolator and a polarization modulator are discussed ...

Anisotropic Airy beams

open access: yesResults in Optics, 2023
Anisotropic Airy beams are presented as solutions to the parabolic wave equation. We obtain the cross polarization terms in the new beams using the elegant Mukunda–Simon–Sudarshan matrix substitution rule for transition from Helmholtz scalar wave optics ...

Polarizing optics in a spider eye [PDF]

open access: yesJournal of Comparative Physiology A, 2010
Many arthropods including insects and spiders exploit skylight polarization for navigation. One of the four eye pairs of the spider Drassodes cupreus is dedicated to detect skylight polarization. These eyes are equipped with a tapetum that strongly plane-polarizes reflected light.

Reconfigurable beams with arbitrary polarization and shape distributions at a given plane [PDF]

open access: yes, 2013
Methods for generating beams with arbitrary polarization based on the use of liquid crystal displays have recently attracted interest from a wide range of sources.

Polarization-maintaining optical microfiber [PDF]

open access: yesOptics Letters, 2010
We have successfully demonstrated a polarization-maintaining (PM) fused silica microfiber by adiabatically tapering a conventional PM fiber. Compared to standard single-mode microfibers, the proposed PM microfibers exhibit robust polarization, preserving characteristics under the presence of external perturbations, such as bending.

Polarization singularities in isotropic random vector waves [PDF]

open access: yes, 2001
Following Nye & Hajnal, we explore the geometry of complex vector waves by regarding them as a field of polarization ellipses. Singularities of this field are the C lines and L lines, where the polarization is purely circular and purely linear ...

Bridging coherence optics and classical mechanics: A generic light polarization-entanglement complementary relation

open access: yesPhysical Review Research, 2023
While optics and mechanics are two distinct branches of physics, they are connected. It is well known that the geometrical/ray treatment of light has direct analogies to mechanical descriptions of particle motion.

Polarization-dependent losses in porous silicon ridge waveguides

open access: yesResults in Optics, 2022
Porous silicon is a material used in integrated optics with few studies on its structuration impact on the polarization in the near infra-red spectral range.

Polarization of Radiation by the Aerosol-Gas Component of the Atmosphere for Lidar Wavelengths [PDF]

open access: yesEPJ Web of Conferences, 2020
The report presents an original algorithm for solving the radiation transfer equation based on the Monte Carlo method for problems of atmospheric laser sensing, taking into account the polarization of radiation.

Effective Surface Roughness Impact in Polarimetric GNSS-R Soil Moisture Retrievals

open access: yesRemote Sensing, 2023
Single-pass soil moisture retrieval has been a key objective of Global Navigation Satellite System-Reflectometry (GNSS-R) for the last decade. Achieving this goal will allow small satellites with GNSS-R payloads to perform such retrievals at high ...
