Abstract

So-called polarization-insensitive optical phase conjugation with four-wave mixing in a dispersion-shifted fiber by the use of two orthogonally polarized pumps is analyzed theoretically. An inherent polarization dependence as a result of polarization-dependent cross talk, asymmetrical depletion of the two pumps and input signal, and polarization-sensitive phase conjugation is identified.
