Invention relates to the physics of polaritons and Bose-Einstein condensates; creation and development of new approaches to solving complex computational problems using simulators based on systems of coupled polariton condensates. In particular, the present invention consists in the development of a system for selectively monitoring the interaction between the nearest nodes (condensates) in a fixed two-dimensional lattice of Bose condensates and the next nearest nodes without changing the geometry of the lattice and the intensity of the radiation exciting the condensates.

Invention relates to fully optical logic elements implemented using the concept of non-equilibrium condensation of exciton-polaritons into a non-basic state. The fully optical logic element includes an organic semiconductor sample placed in a microresonator with a Q-factor in the range from 500 to 600, a coherent source of continuous optical pumping to form an exciton reservoir by non-resonant excitation of the sample, with a pump beam energy to provide a condition for spontaneous condensation of exciton polaritons from an exciton reservoir, a source of radiation of one or two seed pulse beams to stimulate the relaxation process of a hot exciton into a non-basic state of the lower polariton branch.
