Demonstration of Polarization Muiltiplexed Signals Division Using a Fiber Optical Parametric Amplifier

The main goal of this paper is to demonstrate the ability of a single pump parametric amplifier with linearly polarized pumping radiation to divide orthogonally polarized optical signals, by emphasizing a signal with certain state of polarization from a combination of orthogonally polarized signals. In the implemented solution two orthogonally polarized optical signals are placed on the same wavelength, and, after being highly attenuated, processed by the parametric amplifier in such a way, that only a signal with a certain state of polarization is amplified. Such additional application of parametric amplifiers has not been demonstrated so far
