Abstract

We theoretically investigate the plasmonic Talbot effect in monolayer graphene sheet arrays (MGSAs) when surface plasmon polaritons (SPPs) between graphene experience weak coupling. The Talbot effect occurs only when the incident field has a pattern with a few selected periods. The Talbot distance is found to decrease exponentially with the decreasing period of the MGSA and can be as small as 1/20 of the incident wavelength. In addition, the Talbot distance can be further reduced by increasing the chemical potential of graphene or operating at longer wavelengths.
