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

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

Automation of Mode Locking in a Nonlinear Polarization Rotation Fiber Laser through Output Polarization Measurements. [PDF]
J Vis Exp, 2016 When a laser is mode-locked, it emits a train of ultra-short pulses at a repetition rate determined by the laser cavity length. This article outlines a new and inexpensive procedure to force mode locking in a pre-adjusted nonlinear polarization rotation fiber laser.

Nonlinear magneto-optical rotation of elliptically polarized light [PDF]
Physical Review A, 2003 We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically-polarized light propagating in a coherent atomic medium. We show that this effect results from a hexadecapole and higher order momenta of atomic coherence, and is associated with an enhancement of Kerr and higher orders ...

Nonlinear and anisotropic polarization rotation in two-dimensional Dirac materials [PDF]
Physical Review B, 2018 We predict nonlinear optical polarization rotation in two dimensional massless Dirac systems including graphene and 8-$Pmmn$ borophene. When illuminated, a continuous wave optical field leads to a nonlinear steady state of photo-excited carriers in the medium.

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]
, 2012 We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.

All-optical wavelength migration and erasure via nonlinear polarization gating in a TiN/Ti3C2 heterojunction microfiber hybrid device [PDF]
APL PhotonicsConventional all-optical wavelength converters suffer from a fundamental limitation: the residual original signal remains at the output, resulting in spectral inefficiency and potential coherent crosstalk.
