Abstract
Electromagnetically induced transparency (EIT) analog in all-dielectric metamaterials with a high quality factor provides an effective route to enhance light–matter interaction at the nanoscale. In particular, the active control applied to it enables great degree of freedom for spatial light modulation and thus promises functional device applications with high flexible tunability. Here, we load graphene into all-dielectric metamaterials and realize the remarkably high modulation depth in the transmission amplitude of the EIT resonance with the manipulation of graphene conductivity, via shifting the Fermi level or altering the layer number. The physical origin lies in the controllable light absorption through the interband loss of graphene in the near infrared. This work reveals a strategically important interaction mechanism between graphene and EIT resonance in all-dielectric metamaterials, and opens avenues in designing a family of hybrid metadevices that permit promising applications to light modulation, switching, slow light and ultrasensitive biosensing.
