Meta 2010 & FEM 2010 – Rome, 13-15 December 2010 Multistability at arbitrary low optical intensities through epsilon-near-zero nonlinear metamaterial Alessandro Ciattoni (1) , Carlo Rizza (2) and Elia Palange (2) (1) Consiglio Nazionale delle Ricerche, CNR-SPIN 67100 L'Aquila, Italy E-mail: alessandro.ciattoni@aquila.infn.it (2) Electrical Engineering Department, University of L'Aquila, 67100 Zona Industriale di Pile (L'Aquila), Italy We show that a nonlinear metal-dielectric layered slab of subwavelength thickness and very small average dielectric permittivity displays optical multistable behavior at arbitrary low optical intensities. This is due to the fact that, in the presence of the small linear permittivity, one of the multiple electromagnetic slab states exists no matter how small is the transmitted optical intensity. We prove that multiple states at ultra-low optical intensities can be reached only by simultaneously operating on the incident optical intensity and incidence angle. b) a) Figure 1 – a) Transmissivity at two different incidence angles and surface of allowed electromagnetic states. b) Geometry of the metal-dielectric layered slab together with overall slab transmissivity and parameter space region (shaded region) where multistability occurs. Note that multistable states exist no matter how small is the incident optical intensity. References [1] A. Ciattoni, C. Rizza and E.
