TLDR
The potential use of self-induced birefringence effects in a periodically modulated nonlinear medium for relatively low-power intensity discrimination, all-optical polarization switching, and small-signal amplification using linearly polarized beams is described.Abstract:
Self-induced birefringence effects in a periodically modulated nonlinear medium are investigated An input beam linearly polarized along the axis of a fiber polarization-rocking filter undergoes a spatial instability as the input power crosses a threshold value that scales linearly with the coupling strength We describe the potential use of this effect for relatively low-power intensity discrimination, all-optical polarization switching, and small-signal amplification using linearly polarized beams The wavelength for maximum polarization conversion between the axes can be tuned by varying the input power, and the filter bandwidth narrows with increasing powerread more

The nonlinear coherent coupler
TL;DR: The nonlinear coherent coupler (NLCC) as mentioned in this paper is a device useful for optical processing, but not bistable, which utilizes the coherent interaction of two optical waveguides placed in close proximity.

Origins and control of polarization effects in single-mode fibers
TL;DR: In this article, the basic birefringences that couple the two modes and change the polarization state along the fiber are reviewed, and three cases of uniform, phase-matched, and random coupling are considered.

Intensity discrimination of optical pulses with birefringent fibers.
TL;DR: An intensity discriminator for optical pulses can be made with a birefringent fiber using an intensity-dependent state of polarization out of the fiber for separating the intense subpicosecond pulses from the weaker uncompressed background.
