A Low-Complexity Detector for Memoryless Polarization-Multiplexed Fiber-Optical Channels [PDF]

open access: yes, 2013
A low-complexity detector is introduced for polarization-multiplexed M-ary phase shift keying modulation in a fiber-optical channel impaired by nonlinear phase noise, generalizing a previous result by Lau and Kahn for single-polarization signals.

Nonlinear dynamics of mode-locking optical fiber ring lasers [PDF]

open access: yes, 2002
We consider a model of a mode-locked fiber ring laser for which the evolution of a propagating pulse in a birefringent optical fiber is periodically perturbed by rotation of the polarization state owing to the presence of a passive polarizer.

Fluid Models for Kinetic Effects on Coherent Nonlinear Alfven Waves. II. Numerical Solutions [PDF]

open access: yes, 1996
The influence of various kinetic effects (e.g. Landau damping, diffusive and collisional dissipation, and finite Larmor radius terms) on the nonlinear evolution of finite amplitude Alfvenic wave trains in a finite-beta environment is systematically ...

High Nonlinearity and Single-Mode Transmission in Tapered Multimode $\hbox{As}_{2}\hbox{Se}_{3}$-PMMA Fibers

open access: yesIEEE Photonics Journal, 2012
We demonstrate the fabrication and use of a 10-cm-long-PMMA microwire with ultrahigh waveguide nonlinearity γ= 176 W-1 m-1 that is fully compatible with standard single-mode silica fibers.

A Wideband Polarization Observation of Hydra A with the Jansky Very Large Array

open access: yesThe Astrophysical Journal, 2023
We present the results of a wideband high-resolution polarization study of Hydra A, one of the most luminous FR I radio galaxies known and among the most well studied. The radio emission from this source displays extremely large Faraday rotation measures

Nonlinear magneto-optic polarization rotation with intense laser fields [PDF]

open access: yesSPIE Proceedings, 2007
We have studied the nonlinear Faraday effect of intense linear polarized light in an optically thick atomic rubidium vapor. We have shown that the polarization rotatation rate (rotation angle per unit magnetic field, in the limit of low field) reaches a saturation value as the intensity and density are increased.

Control of polarization rotation in nonlinear propagation of fully structured light [PDF]

open access: yesPhysical Review A, 2018
Knowing, and controlling, the spatial polarization distribution of a beam is of importance in applications such as optical tweezing, imaging, material processing and communications. Here we show how the polarization distribution is affected by both linear and nonlinear (self-focussing) propagation.

Quantum control and measurement of atomic spins in polarization spectroscopy [PDF]

open access: yes, 2009
Quantum control and measurement are two sides of the same coin. To affect a dynamical map, well-designed time-dependent control fields must be applied to the system of interest.

Tunable Multiwavelength Passively Mode-Locked Fiber Ring Laser Using Intracavity Birefringence-Induced Comb Filter

open access: yesIEEE Photonics Journal, 2010
A simple configuration for the generation of tunable multiwavelength picosecond-pulse fiber ring lasers by exploiting the intracavity birefringence-induced comb filter is demonstrated.
