Abstract
The bistable properties are investigated in a composite optical configuration based on Fibonacci sequence and nonlinear material. Bistablility is realized near the wavelength of perfect transmission resonance. A small threshold of the switch is attained by introducing a bulk nonlinear defect in the matamaterial photonic bandgap system. Meanwhile, the small offset to the defect mode, the lower threshold of the switch is. When the thickness of the defect layer decreases, multistability is easy to appear if the localized electric field distributed in the form of several isolated centers. Some others, such as the transmission of the linear multilayer and the bistability of band edge states are also calculated by the transfer-matrix method.
