N2 - The normal incidence of circularly polarized optical field (POF) of tunable intensity on the topological insulator Bi2Se3 film is shown to give rise to the quantum spin Hall (QSH) effect, in the presence of the magnetic impurities (MI), starting with a low-energy two-dimensional, time-dependent Hamiltonian in the framework of the Floquet theory. The quantized topological number- the Kane–Mele index Z2 for QSH phase- strongly support this topological state.
