With a decrease in dimensions, a decrease in the thermal coupling action radius is observed, which can vary in the range from 0. 5 to 50 {\mu}m for structures with characteristic dimensions of 0. 1 to 5 {\mu}m, respectively.

In the case of a "weak" coupling, synchronization is accompanied by attraction effect and decrease of the main spectra harmonics width.
