Abstract

The system of equations describing an ultrashort optical pulses propagation in semiconductor superlattice with applied magnetic field was obtained based on Boltzmann equation in the relaxation-time approximation for the single electron distribution function and coupled Maxwell equations for the electromagnetic field. It was demonstrated that an original linear-polarized optical pulse initiates an orthogonal polarization in the field of a sample. The propagation dynamics of initiated and initial pulses in the sample was investigated. The effects of the lattice geometry have been elicited.
