Optical Bistability and Symmetry Breaking at Resonance Scattering of Light by a Finite Photonic Crystal with a Nonlinear Resonant Cavity

Optical bistability and symmetry breaking under the conditions of plane wave incidence on a system of coupled photonic crystal microcavities containing an inclusion with Kerr susceptibility have been studied. The T-matrix modal method has been generalized for the case of nonlinear microcavities supporting one monopole mode. It has been shown that both phenomena considerably depend not only on external field strength but also on angle of incidence and photonic crystal size.
