▎ 摘　　要

The propagation of an ultrashort optical pulse in the multilayered structure formed by alternating graphene and boron nitride layers is considered. Conduction electrons of this system at low temperatures are described by the effective long-wavelength Hamiltonian, and the electromagnetic field is considered based on the classical Maxwell equations. Dependence of the evolution on the ultrashort pulse amplitude and nanoribbon layer width is established.
