  We show fledgling quantum spin Hall phase by the normal incidence of
near-infrared circularly polarized radiation field on Bismuth Selenide doped
with magnetic impurities. For this purpose, we start with a low-energy
two-dimensional, time-dependent Hamiltonian. The time dependence in the
Hamiltonian arises due to the optical field describable by the associated gauge
field. We make use of the Floquet theory in the high-frequency limit to
investigate the system. The optical field tuneability leads to the emergence of
the spin Hall phase, when intensity of the incident radiation is high, from the
quantum anomalous Hall phase. Interestingly, the former phase is achievable
here even in the presence of the magnetic impurities.
