Anisotropic cross talk in an optical interconnection by using a self-pumped phase-conjugate mirror at the Fourier plane

Abstract

Experimental evidence that the cross talk that is due to Bragg degeneracy of the multiplexed volume holograms in a self-pumped phase conjugator at the Fourier plane is reduced along the horizontal direction but not the vertical direction is described. A qualitative explanation is given, and its implication on other anisotropic properties of Fourier-transformed volume holograms under broad conditions is discussed.
