We present the study and design of an optical switch based on a hybrid plasmonic-vanadium dioxide-based waveguide. The power-attenuating mechanism takes advantage of the phase change properties of vanadium dioxide that exhibits a change in the real and complex refractive indices upon switching from the dielectric phase to the metallic phase. The proposed switch was designed to operate under the telecommunication wavelength. The switch was analyzed by three-dimensional full electro-magnetic simulations. An ER per unit length of 4.32 dB / μm and IL per unit length of 0.88 dB / μm are realized for the proposed electro-optical switch. The proposed electro-optical switch has the advantages of small device foot-print, compatible with the existing VLSI-CMOS technology and broadband operation. |
