Abstract

Integrated photonic structures, such as photonic crystal cavities and ring resonators, have proven to be effective nonlinear devices. Here, we review the novel possibilities when multiple cavities are coupled to each other. Their strong and highly tunable feedback properties lead to effects such as switching with very low powers and symmetry breaking bifurcations. These phenomena are useful for all-optical flip-flop devices. The compact nanophotonic structures are efficiently analyzed with coupled-mode theory and rigorous numerical methods.
