Abstract

Based on the discrete sources method, a mathematical model of the plasmon nanolaser resonator deposited on the prism surface in an active ambient medium is developed and implemented, which allows taking into account the non-local effect (NLE) in the plasmon material. The resonator’s characteristics are optimized, which makes 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 is investigated. It is shown that accounting for the NLE leads to a significant decrease in the near-field intensity.

考虑非局域效应的等离子纳米激光谐振腔数学模型

摘要

基于离散源方法，开发并实现了沉积在有源环境介质中的棱镜表面的等离子体纳米激光谐振器的数学模型，该模型允许考虑等离子体材料中的非局部效应 (NLE)。谐振器的特性得到优化，这使得在谐振器的外表面上获得超过两个数量级的场增强成为可能。研究了 NLE 对光谱波长范围内增强的影响。结果表明，考虑到 NLE 导致近场强度显着降低。
