We propose a geometrical model based on the concept of dynamic eigenstates of polarization to describe the behavior of nonlinear polarization rotation (NPR) arising in semiconductor optical amplifiers (SOAs). The rotation axis with respect to either the bias current or the optical power variation is demonstrated on the Poincare sphere (PS), meanwhile a

INFLUENCE OF THE NONLINEAR POLARIZATION ROTATION ON A NONLINEAR FIBER LOOP
Journal of Nonlinear Optical Physics & Materials, 2006A nonlinear fiber loop is considered including four-wave mixing terms. It is shown that these terms lead to considerable modification of the transmission coefficient of the nonlinear fiber loop. The transmission through an output polarizer is also investigated. Very irregular output intensity is obtained when the input intensity is increased.

We present characterization and applications of the nonlinear polarization rotation (NPR) with linear polarization maintenance arising in polarization-insensitive semiconductor optical amplifiers (SOAs). The NPR with linear polarization maintenance is characterized in terms of probe and pump power, bias current, pump polarization, as well as wavelength.

Elimination of nonlinear polarization rotation in twisted fibers
Journal of the Optical Society of America B, 1994It has been previously reported that it is possible to eliminate nonlinear polarization rotation in elliptically birefringent optical fibers. We show that the same can hold true in twisted optical fibers, even though the local eigenmodes are linearly polarized, if the twist length becomes equal to 2 times the beat length.

Passive Polarization Rotators for Nonlinear Optical Devices
MRS Proceedings, 1997AbstractInitial experiments of a passive polymeric TE-to-TM polarization converter that utilizes laterally offset upper and lower poling electrodes to induce a 45° optical axis in the core of a nonlinear optical polymer waveguide are reported. By optimizing the device length, we have demonstrated polarization conversion efficiencies greater than 95% in

Nonlinear polarization rotation and generation of a polarization component orthogonal to the input beam were observed along fourfold axes of YVO4 and BaF2 crystals. We demonstrate experimentally that in both crystals the angle of rotation is proportional, at low intensities, to the square of the product of the input intensity and the crystal length and

Spike suppression in fiber amplifiers through nonlinear polarization rotation
Optics Letters, 2010We report a pulse reshaping approach to suppress the harmful spike in fiber amplifiers. The approach is based on the nonlinear polarization rotation induced by the optical Kerr effect along the fiber. The feasibility and optimization of the pulse reshaping mechanism is analyzed theoretically and experimentally.
