| Abstract: | Evolution of optical pulses, which propagate in strained graphene, has been investigated. The effective wave equation for the vector potential of the electromagnetic field has been derived. The tensile strain of graphene layers has been described using the effective vector-potential in terms of the gauge theory. The numerical solution of the derived wave equation has been presented and the dependence of the pulse strength and shape on the magnitude of the external strain has been analyzed. |
