Four Wave Mixing-Based Time Lens for Orthogonal Polarized Input Signals

We present highly efficient time-lenses for orthogonal polarized signal waves with a specific state of polarization. Our four-wave mixing based time-lenses exploit polarization mode dispersion to compensate for chromatic dispersion. The results reveal that the efficiency of the time-lens is increased fivefold for both states of polarization. We also compensate for any polarization-dependent losses in the system by tailoring the pump state of polarization. Our time-lenses can be implemented in current telecommunication systems together with polarization division multiplexing in order to reach higher bandwidth.
