Polarization attraction process in a dual-Omnipolarizer

Abstract

In this work, we investigate the nonlinear phenomenon of self-attraction of light state-of-polarization in optical fibers by means of dual-Omnipolarizers. More precisely, we compare the performance in terms of polarization attraction efficiency of two different systems: The first configuration relies on a series of two successive Omnipolarizers, whereas the second system includes an imbricated Omnipolarizer into the feedback loop of the main device. Our study reveals that for the same budget of power, the cascading of two Omnipolarizers allows to improve the performance of the polarization attraction phenomenon, leading to an output degree-of-polarization close to unity for any arbitrary polarized input signal.
