  Considering efforts for hot atom vapor-nanophotonic integration as a new
paradigm in quantum optics in this paper we introduce 1D photonic crystal-Rb
vapor cell as structure with miniaturized interaction volume. The Bloch surface
wave excited on surface of a photonic crystal as electromagnetic hosting
photonic mode, and altered the optical response of Rb atoms in the vicinity of
surface. Coupling of atomic states with BSW confined modes would lead to
quantum interference effects and results in nonlinearities in resonant coupling
of atoms with BSW. We show Bloch surface wave induced transparency is highly
stable under a change of incidence angle. Our results show slight changes in
transitions detunings due to nonlinear interactions like the Casimir-Polder
effect under change of localized density of optical states.
