  • Title: Tunable subwavelength photonic lattices and solitons in periodically patterned graphene monolayer.
    Author: Huang C, Ye F, Sun Z, Chen X.
    Journal: Opt Express; 2014 Dec 01; 22(24):30108-17. PubMed ID: 25606939.
    Abstract:
    We study linear and nonlinear mode properties in a periodically patterned graphene sheet. We demonstrate that a subwavelength one-dimensional photonic lattice can be defined across the graphene monolayer, with its modulation depth and correspondingly the associated photonic band structures being controlled rapidly, by an external gate voltage. We find the existences of graphene lattice solitons at the deep-subwavelength scales in both dimensions, thanks to the combination of graphene intrinsic self-focusing nonlinearity and the graphene plasmonic confinement effects.
