Propagating Hybrid Tamm Exciton Polaritons in Organic Microcavity

Abstract

Strong coupling between Tamm plasmons and organic cavity polaritons is observed at room temperature. Angle-resolved reflectometry experiments unambiguously indicate the anticrossing in the dispersion relations, which is characteristic of the strong coupling regime, and the Tamm plasmon−cavity polariton hybrid states can be energetically manipulated by tuning the Tamm plasmons. The experimental data are in good agreement with calculations based on the transfer matrix method. Emission from the lower energy Tamm plasmon−cavity polariton hybrid states is observed, and the propagation property of the hybrid Tamm plasmon polariton is also studied. The real-space imaging experiments reveal that the propagation distance is larger when the Tamm plasmon and cavity polariton are strongly coupled in comparison to both the exciton of the uncoupled organic neat film and the cavity polaritons. Moreover, the propagation length of the hybrid polaritons increases as the fraction of Tamm plasmon component in the hybrid states increases.

The Role of Long-Lived Excitons in the Dynamics of Strongly Coupled Molecular Polaritons

“…To achieve and verify strong coupling in our TIPS-Pc films, we fabricate a planar microcavity and characterize the momentum-energy dispersion of cavity polaritons by angle-resolved reflectivity and photoluminescence (PL) measurements using a Fourier space imaging setup at room temperature. 44 The 160 thick organic film is placed between two metal mirrors to create a Fabry-Perot resonator (inset of Figure 1a). The bottom mirror is optically thick (100 nm) and highly reflective, while the top mirror (air interface) is 30 nm thick and partially transparent.…”

Tamm Plasmon‐Polariton Ultraviolet Lasers

“…In addition, not only the semiconductor materials but also the organic materials have been applied in UV TPP research. [44,45] The UV TPP laser can be used to further realize polariton devices such as polaritronic all-optical logic gates, the critical coupling vortex, [46] the chiral selective emitters, [47] or the tunable bound states in the continuum. [48] Moreover, the UV laser has the potential for biomedical applications such…”

Polariton panorama

“…Common surface plasmon polaritons are formed with a TM polarization at the boundary of metallic and dielectric surfaces and lie to the right of the light cone. Tamm polaritons are found with both TM and transverse electric polarizations, and their dispersion can be within the light cone [492,493].…”
