Extremely Short Optical Pulses

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.

Extremely Short Optical Pulses

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.

Extremely Short Optical Pulses

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.

Extremely Short Optical Pulses

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.

We have considered the problem of evolution of the two-dimensional few cycle optical pulses (FCOP) inside a photonic crystal made of carbon nanotubes. It has been shown that pulse propagation is stable inside the considered environment and it is possible to control and to change the velocity of the pulse propagation by photonic crystal parameters changing.
