Abstract
A theoretical study is performed on the dynamics of extremely short three-dimensional optical pulses in a medium based on carbon nanotubes. The medium has a spatially modulated refractive index and contains a defect (an imperfect photonic crystal). The dynamics of the pulses are modeled numerically. Stable propagation of a pulse in such a medium is established. The effect the parameters of the photonic crystal’s index of propagation (depth and period of modulation, depth and width of the defect) have on the shape of the envelope and the group velocity of the pulse wave packet is determined.
