Abstract: In this paper, we study the evolution of electromagnetic waves in an anisotropic optical medium with carbon nanotubes and polymers. The relevance of the work is due to the active use of such nanocomposites in modern nanophotonics and optoelectronics, where control of femtosecond light pulses is required. The main attention is paid to the influence of anisotropy of optical properties, which occurs due to a certain orientation of carbon nanotubes in a polymer matrix. This phenomenon significantly modifies the nonlinear response of the medium. The system of wave equations for two components for the vector potential is supplemented by a term that takes into account the effect of polymers on an extremely short optical pulse. The dependences of the output pulse parameters on the degree of anisotropy and concentration of nanotubes in the composite are established. It is shown that by controlling the orientation of carbon nanotubes, it is possible to purposefully influence such parameters of an extremely short optical pulse. This opens up significant prospects for the design and creation of new active elements, such as ultrafast optical shutters, modulators, laser radiation limiters and sensors based on controlled nonlinear properties of materials.
