Thermal tuning of mid-infrared plasmonic antenna arrays using a phase change material

We demonstrate that the resonances of infrared plasmonic antennas can be tuned or switched on/off by taking advantage of the thermally driven insulator-to-metal phase transition in vanadium dioxide (VO(2)). Y-shaped antennas were fabricated on a 180 nm film of VO(2) deposited on a sapphire substrate, and their resonances were shown to depend on the temperature of the VO(2) film in proximity of its phase transition, in good agreement with full-wave simulations. We achieved tunability of the resonance wavelength of approximately 10% (>1 μm at λ~10 μm).

We demonstrate a new type of tunable metasurface based on ultra-thin films of phase change materials. Effective optical properties arise from coexistence of a metallic and an insulating phase induced by patterned ion irradiation.
