ABSTRACT:
The tensorial nature of the nonlinear constant or the electro-optic coefficient of the phase conjugate material makes it impossible to perform true phase conjugation of fields with arbitrary polarization states, i.e., to recover the polarization state of the incident light of arbitrary polarization after the phase conjugation. It is demonstrated here that an optical wave propagating through a polarization and mode scrambling medium can regain its original polarization state after phase conjugation followed by reverse propagation through the polarization and mode scrambling medium. Such polarization recovery is achieved even while a magnetic field is applied to the medium, but with power loss proportional to the magnitude of the magnetic field.
