Abstract:   (1140 Views)

In this paper, the all-optical switching controllability in one-dime photonic crystal (1DPC) structure is illustrated. A structure containing  lithium niobate defect layer with  nonlinear response and a pairs of Ag layers for contact electrode with arrangement of (AB)5 Ag LiNbO3 Ag (BA)5 , where A and B are dielectric layers with linear responses is proposed. The linear transfer matrix method in dielectric layers and solving of Helmholtz equation to find the nonlinear responses in nonlinear defect layer are used. Voltage dependent of optical responses in LiNbO3 layer, causes the electrically shifting of the defect mode and the controllability of the linear transmittance spectrum. Also, the nonlinear responses of LiNbO3 cause to tunability of nonlinear responses via the dynamically shifting the optical properties. The frequency shift of the linear defect mode and tunability of bistability threshold with external Voltage are illustrated.
