论文摘要
从理论上讲，我们在超薄跨二维等离子膜附近研究了两级量子偶极子发射极的特性。我们的模型系统模仿固态单光子源设备。使用现实的实验参数，我们将自发和刺激的发射强度曲线作为激发频率和膜厚度的函数，然后分析二阶光子相关性，以探索光子抗激发效果。我们表明，超薄的跨维等离激元膜可以大大改善光子抗挑战，并减小厚度，这使人们可以控制光的量子特性并使其更明显。这些特征的知识对于固态单光子源设备工程和总体而言，对于基于跨维等离子体膜的新集成量子光子材料平台的开发是有利的。
We study theoretically the properties of a two-level quantum dipole emitter near an ultrathin transdimensional plasmonic film. Our model system mimics a solid-state single-photon source device. Using realistic experimental parameters, we compute the spontaneous and stimulated emission intensity profiles as functions of the excitation frequency and film thickness, followed by the analysis of the second-order photon correlations to explore the photon antibunching effect. We show that ultrathin transdimensional plasmonic films can greatly improve photon antibunching with thickness reduction, which allows one to control quantum properties of light and make them more pronounced. Knowledge of these features is advantageous for solid-state single-photon source device engineering and overall for the development of the new integrated quantum photonics material platform based on the transdimensional plasmonic films.
