Abstract
The properties of the polarization operator arising in theoperator method proposed in [1] for the studies of the correlation effects of quantum optics are investigated. This kind of polarization operator indicates the existence in the temperature excited media of bound photonic pairs, formally resembling the associated states of electrons in the theory of superconductivity. To break photonic pairs requires certain energy, reminiscent of the energy gap in the superconductors. The elementary optical excitation in media that occurs when the inclusion of external monochrome disturbance frequency , along with photon pairs and signal frequency also contain signals with a frequency that is formally reminiscent of the Josephson effect. As in the theory of superconductivity, the presence of a medium is required for the formation of coupled pairs. The increase in temperature and concentration of excited atoms of the medium leads to an increase in the number of photon pairs and a loss of thermodynamic stability of the system. The formation of photon pairs manifests itself in all optical effects in excited media. The possibility of propagation of quasi-resonant electromagnetic radiation in dissipative media at a finite temperature with a small absorption is predicted to be unrelated to the laser effect.
