Nonlinear Photonic Crystals as a Source of Entangled Photons

ORAL

Abstract

Nonlinear photonic crystals can be used to provide phase matching for frequency conversion in optically isotropic materials. The phase-matching mechanism proposed here is a combination of form birefringence and phase velocity dispersion in a periodic structure. Since the phase matching relies on the geometry of the photonic crystal, it becomes possible to use highly nonlinear materials. This is illustrated considering implementable one-dimensional periodic structures for the generation of light at wavelengths between 700nm and 1500nm. We show that phase-matching conditions used in schemes to create entangled photon pairs can be achieved in photonic crystals.
