Abstract
We present an electrodynamical model of a quantum plasmonic device--the magneto-optical (MO) spaser. It is shown that a spherical gain nanoparticle coated with a metallic MO shell can operate as a spaser amplifying circularly polarized surface plasmons. The MO spaser may be used in design of an optical isolator in plasmonic transmission lines as well as in spaser spectrometry of chiral molecules.
摘要
我们提出了一种量子等离子体器件——磁光（MO）激光的电动力学模型。结果表明，涂覆有金属 MO 壳的球形增益纳米粒子可以作为放大圆偏振表面等离激元的激光。MO 激光可用于设计等离子体传输线中的光隔离器以及手性分子的激光光谱学。
