Abstract

We present a plasmonic switch based on a combination of plasmonic nanoantennas and a phase-change material such as vanadium dioxide (VO₂) that exhibits great potential for switching the near-field around the nanoantenna at ultrafast time-scales. In order to characterize the switch, we employed the FDTD method to calculate the intensity switching ratio in the vicinity of the nanoantennas, i.e. the ratio of the electric-field intensity between the metallic state (On-state) and the semiconductor state (Off-state) of the VO₂ material. The proposed switch exhibits an intensity switching ratio which is much higher as compared to those reported previously.
