It is shown theoretically and experimentally that a phase-conjugate mirror can be used to compensate for intrasignal photorefractive coupling as well as modal phase dispersion and linear intermodal coupling in a photorefractive fiber. A holographic image stored in a LiNbO3 fiber (at a spatial resolution of 5 line pairs/mm, which is close to the theoretical limit) is successfully reconstructed by compensating for the above factors.
