    "abstract": "Periodic structures consisting of alternating layers of positive index and\nnegative index materials possess a novel band gap at the frequency at which the\naverage refractive index is zero. We show that in the presence of a Kerr\nnonlinearity, this zero-n gap can switch from low transmission to a perfectly\ntransmitting state, forming a nonlinear resonance or gap soliton in the\nprocess. This zero-n gap soliton is omnidirectional in contrast to the usual\nBragg gap soliton of positive index periodic structures",
