The propagation of three-dimensional extremely short optical pulses (light bullets) with a Bessel cross section in a medium of carbon nanotubes placed in an optical resonator is considered. As a result of numerical calculations, it was found that such pulses propagate stably with conservation of energy in a limited region of space, including at large times of the order of 100 ps. Key words: extremely short optical pulses, nonlinear medium, light bullets, carbon nanotubes.

Theoretically investigated the propagation of three-dimensional extremely short optical pulses, the longitudinal Airy cross section in a medium of semiconductor carbon nanotubes under the conditions of an optical resonator. Using numerical simulations, it was found that carbon nanotubes placed in an optical resonator create an environment in which the pulse propagates stably and conserves its energy, and also makes it possible to control some properties of an extremely short pulse (velocity and shape). The calculations of the pulse dynamics were carried out at long times, on the order of 100 ps.

In this paper, we study the behavior of three-dimensional extremely-short optical pulses propagating in a system made of carbon nanotubes in the presence of an external magnetic field applied perpendicular both to the nanotube axis and to the direction of propagation of the pulse. The evolution of the electromagnetic field is classically derived on the basis of the Maxwell’s equations. The electronic system of carbon nanotubes is considered in the low-temperature approximation. Our analysis reveals the novel and unique ability of controlling the shape of propagating short optical pulses by tuning the intensity of the applied magnetic field. This effect paves the way for the possible development of innovative applications in optoelectronics.

We have considered the problem of dynamic propagation of the three-dimensional few-cycle optical pulses of Gaussian and super-Gaussian cross-section inside the Bragg medium with carbon nanotubes. The system has dissipation and additional energy “pumping”. We have shown that the pulse propagation is stable inside the considered environment. The special aspect of the pulse evolution of different cross-sections has been determined.

In this paper, we study the propagation of extremely short electromagnetic pulses in a medium with zig–zag carbon nanotubes taking into account pumping and nonlinear absorption introduced phenomenologically. Based on Maxwell’s equations, we obtain an effective equation for the vector potential of the electromagnetic field, which takes into account the dissipation of the pulse field under the conditions of the piezoelectric effect associated with the vibrations of heavy nuclei of the medium, pumping by an external electromagnetic wave, and nonlinear absorption of carbon nanotubes. We demonstrate the stability of the electromagnetic pulse shape on a time scale that is significantly longer than the pulse duration but not exceeding the relaxation time.
