Abstract: Propagation of the alternating electromagnetic field in a system of zigzagcarbon nanotubes in the case of low temperatures and applied external electricfields are considered. The electronic system of the carbon nanotubes isinvestigated microscopically nonmetering an interaction with a phonon subsystemby the fact that the electromagnetic pulse is critically short. An efficientequation for the vector-potential amplitude of the alternating electromagneticfield is obtained. Solutions of solitons analogs which correspond to solitonsin the case of cosine dispersion law for the electronic subsystem have beenelicited. The dependences of obtained nonlinear solutions on problem parametersand the applied external electric fields were analyzed. The possibility tocontrol the shape of optical pulse in wide range was shown.
