Abstract

Self-pumped photorefractive phase conjugators only work with extra-ordinarily polarized waves (e-waves) with respect to the photorefractive crystal used in the conjugator. This is because photorefractive effect is prominent only with e-wave in crystals. Ordinarily polarized waves (o-waves) do not only give rise to this kind of photorefractive effect but often suppress the e-wave photorefractive effect when both of them are directed into the crystal. In this paper, we propose another photorefractive phase conjugator, which although works with e-waves too, is very insensitive to the suppressing effect of a beam of o-waves occupying the same propagation channel.
