Abstract
Metamaterials provide unique opportunities for manipulation of dispersion of light waves and, therefore, polarisation and phase, as well as amplitude of transmitted and reflected waves. Here we report on using linear and nonlinear properties of nanorod and nanotube based metamaterials for shaping ultrashort optical pulses. Intensity limiters, temporal pulse shape control, as well as polarisation switching will be presented. The role on nonlocal effects in pulse propagation in metamaterials will be discussed. Using nanotube based metamaterials allows to introduce additional degree of freedom for passive and active tunability of the optical response.
