“…( 8), self-energy Σ 21 (t) = pρ 21 (α, t) results in the frequency shift of spectra "−p∆n" without changing the line shapes. 12 One can show that this approach correctly describes the change of the first moment of optical spectra in the condensed matter. Calculations of p for isotropic medium give p = 4π 3 |D 12 | 2 N > 0 12,24,30 that corresponds to a red shift, according to the Clausius-Mossotti Lorentz-Lorentz (CMLL) mechanism.…”

Purely organic materials with negative and near-zero dielectric permittivity can be easily fabricated, and propagation of surface polaritons at the material/air interface was demonstrated. Here we develop a meanfield theory of light-induced optical properties of photonic organic materials taking the collective effects into account. The theory describes both a red shift of the resonance frequency of isolated molecules, according to the Clausius-Mossotti Lorentz-Lorentz mechanism, and the wide variations of their spectra related to the aggregation of molecules into J-or Haggregates. We show that the experimental absorption spectra of H-aggregates may be correctly described only if one takes both mechanisms into account. The bistable response of organic materials in the condensed phase has been demonstrated using the electron-vibrational model. We show that using molecules with long-living triplet state T 1 near excited singlet state S 1 , and fast intersystem crossing S 1 → T 1 enables us to diminish CW light intensity needed for observing bistability below the damage threshold of thin organic films.

“…The analysis shows that it is possible to realize a bistable dependence of populations of levels on laser intensity in the case of dense medium at the blue side of the absorption spectrum [41]. Therefore it is natural to expect existence of switching waves in organic films of sufficient size.…”

Extreme and Topological Dissipative Solitons with Structured Matter and Structured Light

Structuring of matter with nanoobjects allows one to generate soliton-like light bundles with extreme characteristics—temporal duration and spatial dimensions. On the other hand, structuring of light gives the possibility to form light bundles with complicated internal structure; their topology could be used for information coding similar to that in self-replicating RNA molecules carrying genetic code. Here we review the both variants of structuring. In the first variant, we consider a linear molecular chain and organic film interacting resonantly with laser radiation. Demonstrated are optical bistability, switching waves, and dissipative solitons, whose sizes for molecular J-aggregates can reach the nanometer range. We also discuss some theoretical approaches to take into account multi-particle interaction and correlations between molecules. In the second variant, light structuring in large-size laser medium with saturable amplification and absorption is achieved by preparation of the initial field distribution with a number of closed and unclosed vortex lines where the field vanishes. Various types of topological solitons, parameter domains of their stability, and transformation of the solitons with slow variation of the scheme parameters are presented.
