“…Among them the nanolasers, the so-called "Spasers", cause a huge interest [3,4], as well as nanolasers in the ultraviolet range on the basis of aluminum [5]. Moreover, devices in which the plasmon effects are implemented for practical application, in particular for the analysis of biochemical media on the basis of resonance absorption of a surface plasmon-polariton wave [6][7][8] are now under intense researching.…”
