Vortices in generalized Stokes parameters

SPIE Proceedings, 2010
Presence of vortices/phase singularities has been demonstrated in instantaneous generalized Stokes parameters (IGSP) of the field generated by illuminating a random phase screen with a polarization structured beam. Polarization structuring is achieved by focusing the vector beam with tilt in one of the orthogonal polarization components with respect ...

Stokes parameters and Stokes operators

2016
It is shown that the description of polarization based on quantization of classical Stokes parameters is incomplete in quantum domain. For example, the polarization of the electric dipole radiation of the atomic or molecular transitions is described by nine generators of the SU(3) subalgebra in the Weyl-Heisenberg algebra of photons, in other words, by

Statistics of normalized Stokes polarization parameters

Applied Optics, 2018
The normalized Stokes parameters are formed from the ratio of the polarization components to the intensity component of light. Such ratio distributions are known to have an undefined mean and variance, and yet researchers in the polarization community work with these normalized parameters all the time.

Dual-Polarized SAR and Stokes Parameters

IEEE Geoscience and Remote Sensing Letters, 2006
For a given transmission polarization, the four-element Stokes vector captures all of the information inherent to the dual-polarized backscattered signals. Stokes parameters are linear combinations of the like-polarized power, the cross-polarized power, and the cross product between the complex image amplitudes in the two receive channels.

Generalized Stokes parameters in phase space

Optics Letters, 2010
The generalized Stokes parameters (GSP) are studied under the theory of phase space. It is noted that phase-space Stokes parameters can be a useful tool for Wigner distribution function measurements. Electromagnetic Wigner functions are introduced by use of the two-point statistics of GSP.

Classical-Quantum Signaling via Stokes Parameters

GLOBECOM 2024 - 2024 IEEE Global Communications Conference
Catering for the emerging satellite-based free-space optical (FSO) communication networks, exploiting polarization encoding via Stokes operators, we propose a novel simultaneous quantum-classical communications (SQCC) protocol that enables the coexistence of secured quantum communications and high-throughput classical communications under minimal ...

The Stokes Parameters Representation

2011
6.1 Introduction In Chapter 5, we examined the Jones vector representation of polarized light, which is quite simple and straightforward. This representation, however, can describe only polarized light. In this chapter, we discuss a more versatile representation of the polarization state of any light wave (completely polarized, unpolarized, or ...

Measuring the Stokes polarization parameters

American Journal of Physics, 2007
The Stokes formulation for representing polarized light is discussed along with the classical measurement method for determining the Stokes polarization parameters. The limitations of this method are noted, and we consider the rotating quarter-waveplate method, which avoids the limitations of the classical method and allows a curve fitting algorithm to

Evolution of the Stokes parameters in optically anisotropic media

Optics Letters, 1995
The evolution of the Stokes parameters in optically anisotropic media is characterized by a set of coupled nonlinear first-order differential equations. The incident quasi-monochromatic plane-wave field is assumed to be statistically stationary and of arbitrary state of polarization.

Measuring the Stokes Polarization Parameters

2017
The polarization properties of scattered light from turbid media such as biological tissues, human or animal muscle, and certain plastics have received considerable attention due to their potential for use in inspection or diagnostic detection applications. The polarized light state is represented by Stokes parameters and several methods.
