Abstract
Employing geometry dependent plasmon resonances of graphene gratings, we design a graphene bi-layer optical grating, which can achieve several orders of magnitude enhancement of the second-harmonic generation (SHG) intensity. More importantly, this dual grating can act as an ultrafast optical switch as the SHG intensity can be readily controlled via gate voltage tuning.
