“…The obtained single-photon Rabi frequency was in the range of a few gigahertz for the cavity volume less than λ 3 (λ is light wavelength). Such results pave the way to the design of new scalable devices for quantum memory purposes being compatible with photonic circuits [20]; these devices explore two-level systems at their heart [5,[21][22][23].…”

“…Apart from three-level systems which are widely used for quantum memory purposes, the protocol for photon storage based on two-level systems explores direct control of the transition dipole matrix element [21] or atom-light detuning [5,22]. In particular, manipulation with the sign of detuning is supposed to be made in controlled reversible inhomogeneous broadening (CRIB) photonic memory protocol proposed in [22] and then discussed and improved recently in [23].…”

Considering two-level media in the array of weakly coupled nanocavities, we reveal a variety of dynamical regimes, such as diffusion, self-trapping, soliton, and breathers for the wave packets in the presence of photon tunneling processes between the next-nearest cavities. We focus our attention on the low-branch bright polariton soliton formation, due to the two-body polariton-polariton scattering processes. When detuning frequency is manipulated adiabatically, the low-branch lattice polariton localized states, i.e., solitons and breathers evolving between photonlike and matterlike states, are shown to act as carriers for spatially distributed storage and retrieval of optical information.

“…Alodjants et al [13] estimated the information storage fidelity taking into account only changes in wave packet shape, but this is generally insufficient. It is, in addition, necessary to analyse transformations of the quantum state of the optical field with consideration for the structure of the polaritonic crystal and its decoherence (see, e.g., [23]).…”

“…For simplicity, we examine a 1D polaritonic crystal structure below, for which k n = mk x l, where k x is the x-axis projection of the optical field wave vector and l is the lattice constant. Substituting (13) into (10)- (12), we obtain the k-space Hamiltonian…”

We describe a new type of spatially periodic structure (lattice models): a polaritonic crystal (PolC) formed by a two-dimensional lattice of trapped two-level atoms interacting with quantised electromagnetic field in a cavity (or in a one-dimensional array of tunnelling-coupled microcavities), which allows polaritons to be fully localised. Using a one-dimensional polaritonic crystal as an example, we analyse conditions for quantum degeneracy of a low-branch polariton gas and those for quantum optical information recording and storage.

We propose a new type of spatially periodic structure, i.e. polaritonic crystal (PolC), to observe a "slow"/"stopped" light phenomenon due to coupled atom-field states (polaritons) in a lattice. Under the tightbinding approximation, such a system realizes an array of weakly coupled trapped two-component atomic ensembles interacting with optical field in a tunnel-coupled one dimensional cavity array. We have shown that the phase transition to the superfluid Bardeen-Cooper-Schrieffer state, a so-called (BCS)-type state of low branch polaritons, occurs under the strong coupling condition. Such a transition results in the appearance of a macroscopic polarization of the atomic medium at non-zero frequency. The principal result is that the group velocity of polaritons depends essentially on the order parameter of the system, i.e. on the average photon number in the cavity array.
