The strong coupling between the exciton polariton and the plasmon polariton produced by the interaction of light and matter forms a new hybrid polariton. We investigated the interaction between black phosphorus and metal generated polaritons. The spectrum with angular resolution as a variable shows anti-crossing characteristics in the strong coupling region. The proposed structure can achieve 65–150meV Rabi splitting. The dispersion relation and coupled harmonic oscillator model also prove that increasing dielectric permittivity can effectively enlarge Rabi splitting. The research provides a backdrop for the application of polarization devices and strong coupling platforms.

激子极化子与光与物质相互作用产生的等离子体极化子之间的强耦合形成了一种新的混合极化子。我们研究了黑磷和金属产生的极化子之间的相互作用。以角分辨率为变量的光谱在强耦合区表现出抗交叉特性。所提出的结构可以实现 65-150meV 的 Rabi 分裂。色散关系和耦合谐振子模型也证明增加介电常数可以有效地扩大拉比分裂。该研究为偏振器件和强耦合平台的应用提供了背景。
