    Abstract

    We demonstrate two different platforms and strategies for creating highly tunable VO2-based building blocks for a multi-application metamaterial-based optical system. Our first strategy is based on VO2 nanocrystals (NCs) embedded in SiO2, in which we show that the multipole resonances supported by VO2 NCs can be actively tuned by its insulator-to-metal transition (IMT) and tailored according to its size. Our second strategy is based on the integration of a VO2 layer coupled to a dielectric metasurface consisting of silicon (Si) resonators, where the interaction between these resonances and the incident light can be tuned depending upon the transition state of the VO2.
