Discrete and surface solitons in photonic graphene nanoribbons.
We analyze localization of light in honeycomb photonic lattices restricted in one dimension, which can be regarded as an optical analog of graphene nanoribbons. We discuss the effect of lattice topology on the properties of discrete solitons excited inside the lattice and at its edges. We discuss a type of soliton bistability, geometry-induced bistability, in the lattices of a finite extent.
