Abstract
In this work, we experimentally demonstrate light-by-light polarization control for Telecom applications via a nonlinear interaction occurring in single mode fiber between a signal beam and a counter-propagating control pump wave. In particular, we observe an attraction and stabilization process of the state of polarization (SOP) of a 10-Gbit/s optical telecommunication signal around 1550 nm for either on/off keying (OOK) and non return-to-zero (NRZ) modulation formats. In a second section, we extend our device to 40-Gbit/s by experimentally combining an all-optical regeneration of both the polarization state and the intensity profile of a 40-Gbit/s OOK signal in a single segment of fiber. These experimental results confirm yet another fascinating way to all-optical control light features within optical fibers.
