title: Ultralow threshold optical bistability in metal/randomly layered media structure.
abstract: The Tamm plasmon polaritons (TPPs) at the metal/randomly layered media (RLM) structure were studied. The optical bistability was realized by replacing one of the RLM components of the Kerr nonlinear material. An ultralow switching threshold of 44  kW/cm2was obtained, due to the field enhancement through the resonant transmission in the RLM and TPPs. A theoretical analysis was presented, matching the numerical simulation result well. The bistability threshold was found to be related to the mismatch in the excitation frequency of TPPs, the thickness of metal film, and the intensity of nonlinear response.
