Abstract: (2566 Views)
In this paper, a multilayer plasmonic electro-optical absorption modulator is introduced based on two active layers of barium titanate (BaTiO3) and Indium tin oxide (ITO). It is assumed that the BaTiO3 layer is a birefringent crystal and the Pockels effect occurs in this layer while the free carrier dispersion effect takes place in the ITO layer. Here, we study the effects of the thicknesses of the active layers on the modulator performance. By applying voltage to the silver layers, therefore, an electrical field is formed in the two active layers and the refractive indices of the layers are changed. In order to simulate this modulator, the Nelder-Mead method is implemented to solve the obtained dispersion equation for the proposed multilayer structure at the wavelength of 1.55 µm. Our simulation results indicate that the proposed structure can be used as a plasmonic electro-optical modulator.
