Abstract
"In this paper, we consider the dynamics of three-dimensional extremely short optical pulses in a medium with a spatially variable refractive index (photonic crystal) based on carbon nanotubes. The transitions between impurity levels in carbon nanotubes are taken into account. It has been established that pulses propagate stably with conservation of energy in a limited region of space. The effect of modulation parameters of the refractive index of a photonic crystal on the shape and group velocity of the pulse wave packet is obtained. The rate of one- and two- photon ionization in such medium is estimated."
