Abstract

We theoretically analyze the nonlinear phase shifts induced by cascaded χ(2)(2) processes in one-dimensional photonic bandgap structures. We find that the enhancement of the density of modes near the band edge, coupled with a suitable choice of relative phase mismatch, leads to a remarkable new effect: The relative phase shift of the fundamental field on transmission can be of the order of π over a distance of 7μm , with input intensities of the order of only 10 MW/cm2.
