Summary: This paper discusses the exploration of two-dimensional materials for optoelectronic applications in the past decade and highlights their optical and electronic properties. Integration with other two-dimensional materials or plasmonic metal nanostructures is shown to enhance light absorption efficiency and influence electronic properties. Additionally, the optoelectronic properties of plasmonic nanostructure integrated two-dimensional heterostructures are also overviewed.

Summary: By optimizing the strong coupling between perovskite excitons and quasi-bound states in the continuum, supported by an all-perovskite metagrating with high-quality factor, it is possible to achieve a record high Rabi splitting value. The thickness of the perovskite metasurface and the Q-factor of the QBIC mode play dominant roles in enhancing the strong coupling.

Summary: The unique properties of 2D materials make them suitable for the design of novel optoelectronic devices. This study presents a prototype of a modulator that uses tunable anisotropic borophene plasmons to modulate graphene electroabsorption. The results show excellent performance and potential for designing graphene-based switches or modulators.

Summary: This paper investigates the dynamics of hybridized states from 2D Ruddlesden-Popper perovskites coupled to plasmonic nanoparticle lattices. The coupling strength can be modulated by varying the perovskite film thickness or the superstrate refractive index. The study shows that both upper and lower polaritons have shorter lifetimes than excitons and polaritons exhibit faster excited-state dynamics when they have access to additional energy transfer channels.

Summary: Strong exciton-plasmon coupling between MoS2 layers and a bowtie gap mode was achieved using gold-assisted mechanical exfoliation and nondestructive wet transfer techniques, reducing the effective exciton number and paving the way for strong coupling with a small number of excitons in 2D materials at room temperature.

Summary: In this study, we demonstrate the strong coupling of surface plasmon modes of metal nanowires and excitons in monolayer semiconductors, and validate this coupling through theoretical calculations and experimental results. These findings contribute to a deeper understanding of the spectral phenomena in the plasmon-exciton strong coupling regime.

Summary: We report the detection of plasmon-enhanced Raman scattering (PERS) in self-assembled AgxC60 nanocomposite films and investigate the evolution of this effect with increasing Ag concentration, x, in the range of 2 < x < 25. The PERS effect is found to be closely related to the dipolar plasmonic mode generated by uniform 3D-ensemble of Ag nanoparticles in the C-60-based matrix. The analysis of absorption spectra reveals strong coupling between the dipolar plasmon mode and the C-60 low-energy exciton, indicating energy exchange between high- and low-energy polaritonic states. The obtained PERS spectra show sensitivity of the C-60 vibrational modes to the plasmonic field strength, which can be tuned by adjusting the Ag concentration.

Summary: The study demonstrates that high-quality multi-band absorption can be achieved by coating periodic monolayer graphene nanoribbons on an all-dielectric nanostructure. The system shows high tunability and large near field enhancement by changing the grating period and Fermi level. Delicate optimization results in high-Q resonances and absorption stability, with an absorption efficiency of up to 97% reached after altering the carrier mobility of graphene.

Summary: The strong coupling between guided mode resonance of dielectric grating and excitons in perovskite film enables significant Rabi splitting, with a maximum of 362 meV achieved by changing the grating period. Effects of structure dimensions on the strong coupling and further enlarging Rabi splitting up to 378 meV by increasing perovskite film thickness are investigated. This novel scheme provides theoretical guidance for perovskite-based light-matter interactions and related studies on quantum and nonlinear photonic devices.

Summary: By exploiting momentum space topology, topological control of 2D perovskite emission in the strong coupling regime via polaritonic bound states in the continuum (BICs) is demonstrated, with observation of polarization singularities and achieving high degree of circular polarization in symmetry-broken structures. Lower polariton modes shifting to low-loss spectral region in strong coupling regime results in strong emission enhancement and large degree of circular polarization.

Summary: In this study, the coupling of plasmons and vibrational modes in a model system of molecular layers on graphene was investigated using a non-Hermitian framework. It was found that the transition point between strong and weak coupling regimes coincides with the exceptional point of non-Hermitian physics. By changing the incident angle of light and the graphene Fermi energy, the exceptional point can be conveniently located, leading to enhanced spectral sensitivity with small changes in molecular film thickness.

Summary: The study investigates strong coupling between excitons in monolayer WS2 and quasi-bound states in the continuum using asymmetric titanium dioxide nanobars. By shaping the metasurfaces and adjusting the incident light angle, a remarkable spectral splitting and typical anticrossing behavior of the Rabi splitting can be observed. The balance between the line width of the quasi-BIC mode and local electric field enhancement is crucial for strong coupling effects in metasurface devices.

Summary: Subwavelength electromagnetic field localization has been the focus of photonic research in the last decade, showing potential for enhancing sensing capabilities and increasing coupling between photons and material excitations. Research has revealed a limit to the possibility of arbitrarily increasing electromagnetic confinement in polaritonic systems. Strongly subwavelength fields can excite high-momentum propagative magnetoplasmons, leading to nonlocal polaritonic effects.

Summary: In the past decade, there has been a surge of interest in using hybrid light-matter states to control the properties of matter and chemical reactivity. Experimental and theoretical studies have shown that these hybrid states can enhance properties like transport, magnetism, and superconductivity, as well as modify (bio)chemical reactivity. This multidisciplinary field has great potential for further exploration.
