摘要：
The nonlinear process of propagation of optical pulses in the spectral region inside the polarization gap in carbon nanotubes has been investigated. A simultaneous solution of the Maxwell equation and the equation of motion for exciton polarization has been carried out. The dynamics of an electromagnetic pulse has been examined as a function of the parameters of the problem. It is shown that taking exciton polarization into account does not have a substantial effect on the propagation process, but alters the shape of the optical pulse.
