Nonlinear optical loop mirror using the nonlinear polarization rotation effect

Optics Communications, 1997
Abstract The effect of nonlinear polarization rotation in a fiber loop mirror constricted from a low-birefringent fiber was numerically examined. We have shown that it provides in itself the intensity variation of the transmission coefficient from 1 to 0 in the configuration with a 0.5 0.5 coupler and a birefringent bias rotating polarization ...

Study of nonlinear polarization rotation in semiconductor optical amplifiers

OECC/ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology, 2008
We proposed a geometrical model to describe the NPR in SOA. There exists PSPv and PDGv. Their expressions with regard to parameters of SOA are obtained. Theoretical results accord well with the experimental data.

Photonic generation of triangular pulses based on nonlinear polarization rotation in a highly nonlinear fiber

Optics Letters, 2014
We propose a novel method to generate triangular pulses based on the nonlinear polarization rotation (NPR) effect in a highly nonlinear fiber. A continuous wave probe beam is polarization-rotated by an intensity-modulated control beam via the NPR effect.

Optimization of pulse shaping using nonlinear polarization rotation

Optics Communications, 1995
Pulse shaping using nonlinear polarization rotation has been analyzed in detail. It is found that there is an optimal, power-dependent polarization ellipticity for the maximum nonlinear transmission. It is also found that the polarization ellipticity should be kept smaller than 0.414 so that higher nonlinear transmission can be obtained.

A Novel OCDMA Thresholder Based on Nonlinear Polarization Rotation

2009 Symposium on Photonics and Optoelectronics, 2009
A novel low-power and cost-effective OCDMA thresholder based on nonlinear polarization rotation (NPR) is proposed. The excellent performance and feasibility of the NPR thresholder are experimentally demonstrated in our 2.5 Gb/s ultrashort pulse OCDMA system.

Demonstration of simultaneous nonlinear polarization rotation and dispersive bistability

Nonlinear Optics (NLO), 2019
We experimentally demonstrate the simultaneous occurrence of two nonlinear optical phenomena – nonlinear polarization rotation and dispersive optical bistabilty. The Stokes parameters exhibit bistable hystereses corresponding to a measured orthogonality of 30%.

Polarization-dependent output states of a fiber laser with nonlinear polarization rotation

Optical Engineering, 2008
A fiber laser with two different polarization-dependent output states is demonstrated. On the one hand, intensity-dependent loss in a nonlinear optical loop mirror, induced by nonlinear polarization rotation, can balance mode competition of a homogeneous broadening gain medium, and thus allows for stable room-temperature multiwavelength generation.

Nonlinear phase and polarization rotation noise in fully loaded WDM systems

2015 European Conference on Optical Communication (ECOC), 2015
We show that nonlinear interference noise (NLIN) produced by faraway WDM channels is dominated by nonlinear phase-noise and polarization-rotations, whereas NLIN produced by nearest channels tends to be more circular. We discuss the impact of these results on nonlinear mitigation.

Optical switching using nonlinear polarization rotation inside silicon waveguides

Optics Letters, 2009
We study the nonlinear polarization rotation induced by a pump pulse on a probe beam through cross-phase modulation inside a silicon waveguide and show that this phenomenon can be used to realize a fast Kerr shutter in spite of the free-carrier effects and walk-off.

Numerical analysis of the nonlinear polarization rotation mode-locked pulses in fiber

SPIE Proceedings, 2011
In the nonlinear polarization rotation (NPR) mode locking fiber laser, the electric fields of different intensity of pluses will have different nonlinear phase shifts because of self phase modulation (SPM) and cross-phase modulation (XPM) effects. In this paper we analysis the SPM and XPM effect on the characteristics of pulses in fiber which were ...
