▎ 摘  要

A theory of optical solitons under the condition of nonlinear coherent interaction of surface TM-modes with a two-dimensional layer of semiconductor quantum dots and a graphene monolayer (or graphene-like two-dimensional material) is developed. Explicit analytical expressions for a surface soliton (2 pi pulse) of self-induced transparency are obtained. It is shown that the optical conductivity of graphene reduces the amplitude of the surface soliton in the process of propagation. (C) 2014 Elsevier B.V. All rights reserved.
