Paper Abstract

We investigate quasi-phase-matching (QPM) and spontaneous parametric down-conversion in randomly poled structures. The novelty is that we consider the disordered structure which involves nonlinear segments separated by domains with linear optical spacers of random lengths. Considering down-conversion, we calculate the probability of production of pair photons by using the procedure of averaging over random positions of domains boundaries. We demonstrate the method of compensation of the dispersive effects in nonlinear segments by appropriately chosen linear dispersive segments of superlattice for realizing effective QPM and preparation of joint states of two photons.
