Intense ultra-broadband down-conversion from randomly poled nonlinear crystals

Abstract

Randomly poled nonlinear crystals are shown to be able to emit intense ultra-broadband photon-pair fields with properties comparable to those coming from chirped periodically-poled crystals. Their intensities scale linearly with the number of domains. Also photon pairs extending over intervals with durations comparable to one optical cycle can be generated in these crystals.
