All-optical Control of Polarization State in Optical Fibers for Telecommunication Applications

subject

description

International audience; In this work, we report last developments in all-optical nonlinear control of polarization state in optical fibers based on a counter-propagating four-wave mixing interaction. In particular, we will show that it is possible, using a unique segment of fiber, to all-optically manipulate both the polarization state and intensity profile of telecommunication signals. We will also report significant results dealing with a new pump-free configuration, which give rise to a much easy to implement promising device.
