Abstract

This review is devoted to the study of effects of quantum optics in nanostructures. The mechanisms by which the rates of radiative and nonradiative decay are modified are considered in the model of a two-level quantum emitter (QE) near a plasmonic nanoparticle (NP). The distributions of the intensity and polarization of the near field around an NP are analyzed, which substantially depend on the polarization of the external field and parameters of plasmon resonances of the NP. The effects of quantum optics in the system NP + QE plus external laser field are analyzed-modification of the resonance fluorescence spectrum of a QE in the near field, bunching/antibunching phenomena, quantum statistics of photons in the spectrum, formation of squeezed states of light, and quantum entangled states in these systems.

摘要

本综述致力于研究纳米结构中量子光学的效应。在等离子体纳米粒子（NP）附近的两能级量子发射体（QE）模型中，考虑了辐射和非辐射衰减率被修改的机制。分析了NP周围近场强度和偏振的分布，其很大程度上取决于外部场的偏振和NP的等离子体共振参数。分析了NP + QE加外部激光场系统中的量子光学效应——近场中QE共振荧光光谱的修改、聚束/反聚束现象、光谱中光子的量子统计、光压缩态的形成以及这些系统中的量子纠缠态。
