In this work, we considered the evolution of extremely short optical pulses in a photonic crystal of semiconductor carbon nanotubes placed in an external pumping field. The possibility of stable propagation of electromagnetic pulses under conditions of a pumping and damping field, due to the balance of dissipative forces and an external field, is shown. The stability of the shape of an extremely short optical pulse at long times is demonstrated with a change in various parameters of the medium, such as the period of inhomogeneity of carbon nanotubes in a photonic crystal and the modulation depth of the refractive index.
