Numerical analysis of the functional properties of the 3D resonator of a plasmon nanolaser with regard to nonlocality and prism presence via the Discrete Sources method
Abstrak
The influence of the nonlocality effect on the optical characteristics of the near field of a plasmonic nanolaser resonator is considered. A computer model based on the Discrete Sources method has been developed for the analysis of the near-field characteristics of a layered nanoparticle located on a transparent substrate in an active medium. In this case, the nonlocality of the plasmon metal is taken into account within the framework of a Generalized Nonlocal Optical Response model. Excitation of a particle by both propagating and evanescent waves is investigated. "Optimal" directions of external excitation have been established. It is found that excitation by an evanescent wave leads to a higher intensity of the near field. It is demonstrated that accounting for the nonlocal effect in the plasmonic metal significantly reduces the field amplification factor.
