Hybrid Plasmonic Electro-Optical Absorption Modulator Based on phase change characteristics of vanadium-dioxide

摘要

This work presents the study and the design of optical switch based on a hybrid plasmonic-vanadium dioxide basedwaveguide. The power-attenuating mechanism takes the advantage of the phase change properties of vanadium dioxidethat exhibits a change in the real and complex refractive indices upon switching from the dielectric phase to the metallicphase. The proposed switch designed to operate under the telecommunication wavelength. The switch was analyzed by3D full electro-magnetic simulations. An ER per unit length of 4.32 dB/μm and IL per unit length of 0.88 dB/μm arerealized for the proposed electro-optical switch. The proposed electro-optical switch has the advantages of small devicefoot-print, compatible with the existing VLSI-CMOS technology and broadband operation.
