Photorefractive phase conjugators and their applications

Abstract

We present a general survey on phase conjugators including self-pumped phase conjugator (SPPC) and mutually pumped phase conjugator (MPPC) in photorefractive BaTiO 3 crystal along with some recent results on two high-performance phase conjugators using pentagon-shaped BaTiO 3 crystal. We also describe two unconventional conjugators with highly ordinary polarized and purely ordinary polarized incident beams. Finally, an application of phase conjugators in one-and two-way 2-D image transfer in optical interconnection is presented.
