| Abstract: | The transmission spectra of two-period metal-dielectric structure are studied through the transfer matrix method. When the dielectric is nonlinear material, an optical bistability has been found. The upper threshold value is insensitive to incident frequency, while the lower threshold value increases with the incident frequency decreasing. The effect of loss from the metal layers on the optical bistability is also considered. |
