摘要：
We have numerically investigated optical bistability (OB) in a TaFD9 prism/Ag film/PDA-4BCMU film/air geometry. 4BCMU films are dealt as nonlinear optic films with Kerr nonlinearity. In the geometry of our interest Surface plasmon polaritons and guided waves can be excited. Numerical calculations have been carried out for TE- and TM-polarized incident lights. In the case of guided waves the critical power density required for OB is less than 1 W/cm2 under a certain condition. This is a promising value to realize actual optic devices.
