In this study, the light–matter interaction between graphene and surface plasmon polaritons (SPP) was investigated. For realizing improved integration in nanocircuits, single-layer graphene was added to asymmetric SPP nanoantenna arrays for nonscattering detection in the near field. The developed device is capable of detecting the controlled propagation of SPPs with a photoresponsivity of 15 mA/W, which paves the way for new-generation on-chip optical communication.
