Mathematical model of plasmon nanolaser resonator accounting for the non-local effect

Based on the Discrete Sources method, a mathematical model of the plasmon nanolaser resonator deposited on the prism surface in an active ambient medium has been developed and implemented, which allows to take into account the Non-local Effect (NLE) in plasmon material. The resonator characteristics were optimized, which made it possible to obtain a field enhancement on the external surface of the resonator by more than two orders of magnitude. The influence of the NLE on the enhancement in the spectral wavelength range was investigated. It has been shown that accounting for the NLE leads to a significant decrease in the near-field intensity.
