title: Bulk plasmon-polariton gap solitons in defective metamaterial photonic superlattices.
abstract: We show the existence of a defect mode within the plasmon-polariton gap in 1D defective photonic superlattices, composed by alternating layers of conventional dielectric (A) and negative refractive (B) material slabs with a dielectric defective layer (D), which, in the nonlinear regime, can be tuned by means of the incident field intensity. Also, we have shown that the self-induced transparency phenomena can be only observed when gap-soliton modes, coupled through the defective layer, are excited in both mirror systems around the defective slab.
