Optical approach to concurrence and polarization

Optics Letters, 2018
We address a recently established relationship, C2+P2=1, which engages concurrence (C) and polarization (P). This relationship has revealed a striking connection between two seemingly unrelated measures. Indeed, while C quantifies entanglement, which is widely seen as a quantum information resource, P quantifies the amount of coherence between optical ...

Polarized Optical-Flow Gyroscope

2020
We merge by generalization two principles of passive optical sensing of motion. One is common spatially resolved imaging, where motion induces temporal readout changes at high-contrast spatial features, as used in traditional optical-flow. The other is the polarization compass, where axial rotation induces temporal readout changes due to the change of ...

Disorientated optical polarization devices

Optics Letters, 2011
By using a pure operatorial (nonmatrix) approach to some of the variable composite polarization devices, we show that for some values of the variable internal parameters, these devices lose their anisotropy. Their principal axes, or more generally their eigenvectors, become undetermined, i.e., in this sense, the anisotropic devices get "disorientated."

Polarization optics of liquid-core optical fibers

Applied Optics, 1977
Whereas straight liquid-core optical fibers have the capability of transporting linearly polarized light with any incident polarization angle,bent fibers exhibit form birefringence with the principal axes fixed to the plane of curvature. The effect of this curvature-dependent birefringence can be compensated by either periodically altering the plane of

Elasto-optic polarization measurement in optical fiber

Optics Letters, 1981
A method is described for the nondestructive determination of the state of polarization of the guided light at an arbitrary point along a single-mode fiber. The fiber is squeezed laterally with a small, periodic (75-Hz) force. The azimuth of the force is varied.

Polarization recovery in optical polarization shift-keying systems

IEEE Transactions on Communications, 1997
For the first time, a solution to the problem of recovering and tracking the signal constellation at the receiver side for binary and octonary digital optical transmission systems employing the modulation of polarization (POLSK) is proposed and analyzed.

Polarization singularities in optical lattices

Optics Letters, 2004
Polarization singularities are shown to be unavoidable features of three-dimensional optical lattices. These singularities take the form of lines of circular polarization, C lines, and lines of linear polarization, L lines. The polarization figures surrounding a C line (L line) rotate about the line with winding number +/-1/2 (+/-1).
