The active photonics based on the two-dimensional material graphene have attracted a great deal of interest for developing tunable and compact optical devices with high efficiency. Here, we integrate graphene into the Fano-resonant all-dielectric metasurfaces consisting of silicon split resonators, and systematically investigate the strong interaction between graphene and the highly localized hot spots inside feed gaps in the near infrared regime. The numerical results show that the integrated…
