Recently, dynamic metasurfaces have attracted significant attention due to their ability to actively control electromagnetic waves upon external tunings. The realization of high performance dynamic metasurfaces-based devices remains a great challenge due to very limited modulation depths. Here based on the Huygens metasurfaces, the high efficient active control of transmitted wave was realized by the combination of dielectric resonators and a phase transition material (vanadium dioxide, VO2). At Huygens-mode wavelength, the metasurface demonstrated 82.5% transmission and ~80% modulation depth. Besides, it exhibits angle-sensitivity and polarization-independence under normal incidence. The proposed metasurface provides a new way for optical switching, filtering, passive temperature control modulation, which would possess broad application prospects for integrated optical devices, near-infrared photodetection, and smart temperature control systems. |
