... The appearance of two energy branches with the upper polariton (UP) and the lower polariton (LP) branches can be found, and the minimum energy difference between the two branches is called Rabi splitting energy (Ω). The flat mode at the exciton energy in Fig. 5(b-f) indicates that parts of the PEPI exciton can be coupled to the photon mode, and the residual exciton outside the vicinity of the hot-spot field cannot be effectively coupled to the SLR, thus the uncoupled exciton remains in the flat modes [15,64]. In Fig. 5(b), when the height of Al NPs is changed from 20 nm to 120 nm, the polariton branches move to high energies, resulting in a decrease in the Rabi splitting energy to 264.23 meV. ...

... Recently, the relationships between the CLRs and the BICs have been of increasing interest. For example, Trinh et al. numerically showed the coexistence of a plasmonic CLR and two symmetry-protected BICs (s-BICs) emerging from the guided resonance confined within the superstrate [20]. The second interesting relationship is that a BIC can be formed by the destructive interference between the electric dipole (ED) CLRs supported by two individual single-particle arrays. ...
