High quality factor nonreciprocal thermal radiation in a weyl semimetal film via the strong coupling between tamm plasmon and defect mode

High Sensitivity Hydrogen Sensor via the Coupling of Tamm Plasmon Polaritons and Defect Mode

“…The defect layer is a SiO 2 layer with a thickness of d 3 = 0.18 µm located below the fourth layer of the photonic crystal. It works by destroying the periodicity of the photonic crystal and forming a photonic local field, which leads to a coupling of defect modes and TPPs and enhances the local field [36,37]. The material forming the spacer layer is SiO 2 (d 4 = 0.054 µm), which strengthens the stability and durability of the structure by introducing a layer of SiO 2 between the photonic crystal and the metal layer [38].…”

Weyl semimetal mediated epsilon-near-zero hybrid polaritons and the induced nonreciprocal radiation

“…What's more important, the dispersion of WSM polaritons and the AlN ENZ mode can intersect with each other near λ ENZ , resulting in the feasibility of strong coupling. 60,61 Fig. 2(b) shows R spectra of the combined WSM-ENZ mode, revealing substantially modified reflection features.…”

Hybrid Tamm and quasi-BIC microcavity modes

“…The TPP can be coupled with other types of modes, with their simultaneous excitation in the system. [22][23][24][25][26] In this case one speaks of hybrid TPP modes. For example, when a PhC with a defect is coated with a metal layer, the TPP mode is coupled with the defect mode or, in other words, with the microcavity (MC) mode.…”
