Summary: By exploiting the highly localized field enhancement in the near field, we demonstrate strong coupling in a dielectric-metal hybrid structure consisting of a perforated silicon nanoblock filled with a slotted silver nanodisk (nanoprism) at its center. This leads to a large Rabi splitting of 275 (262) meV, thanks to the generation of new hybrid energy states through strong anapole-plasmon coupling. Our findings offer a practical approach for achieving large Rabi splitting and provide an attractive platform for exploring the strong coupling regime in light-matter interaction.

Summary: This study demonstrates a strong coupling system achieved by coupling localized surface plasmon modes. Under specific conditions, a root N scaling of Rabi splitting energy is observed, along with a confirmed giant Rabi splitting in the visible spectral range. Additionally, the coupling strength reaches the ultrastrong coupling regime in some cases, representing about 10% of the mode energy.

Summary: This paper presents planar microcavities that are fully processed from solution, consisting of polymer-based distributed Bragg reflectors (DBRs) and a perylene diimide derivative (b-PDI-1) film. Strong light-matter coupling is achieved in these structures, as demonstrated by the energy-dispersion relation in reflectance and the group delay of transmitted light. The controllable production of the entire microcavity stack and the ability to precisely manipulate the refractive index of the inorganic/organic hybrid layers make it possible to design and produce microcavities with a wide spectral range of optical modes.

Summary: This study examines the photodissociation dynamics of an ensemble of diatomic molecules resonantly coupled to a resonant optical cavity under strong coupling conditions at normal incidence. The coupled Maxwell-Schrodinger equations are numerically integrated to account for the molecular ro-vibrational degrees of freedom. It is shown that driving the system at its polaritonic frequencies significantly affects and slows down the dissociation, with no classical analog. An intuitive explanation for the dissociation slowdown at polaritonic frequencies is proposed.

Summary: The study investigates the interaction between black phosphorus and metal-generated polaritons, revealing anti-crossing characteristics in the strong coupling region in the spectrum with angular resolution as a variable. The proposed structure can achieve a Rabi splitting of 65-150 meV, and increasing dielectric permittivity effectively enlarges the Rabi splitting, as demonstrated by the dispersion relation and coupled harmonic oscillator model. This research lays the foundation for the application of polarization devices and strong coupling platforms.

Summary: In this paper, we achieve strong light-matter coupling between a surface plasmon and two organic emitters, resulting in hybrid materials with bifunctionality properties. The optical properties of the materials are drastically modified between activated and deactivated forms of a photochromic material coupled to a cyanine dye, allowing for a tunable emission system. Light-matter interaction is shown to have the potential for modifying the fluorescence of photochromes without the need for covalent bonding.

Summary: Exciton-polariton condensation has been experimentally and theoretically demonstrated to form coherent superposition of exciton-polariton orbital states in halide perovskite semiconductor microcavities at room temperature by engineering artificial annular potential landscapes. The petal-shaped polariton condensates can be precisely controlled by tuning the annular potential geometry, and exhibit locked alternating pi phase shifts and vortex-antivortex superposition cores. This study opens up possibilities for topological polaritonic devices and optical polaritonic switches based on periodic annular potentials in geometrically patterned microcavities.

Summary: Rabi-like splitting and self-referenced refractive index sensing have been theoretically demonstrated in hybrid plasmonic-1D photonic crystal structures. The coupling between Tamm plasmon and cavity photon modes is achieved by incorporating a low refractive index spacer layer. The modes coupling exhibits Rabi-like splitting with different splitting energy, supported by coupled mode theory. The polarization splitting of the lower hybrid mode is stronger than that of the upper hybrid mode. The hybrid modes can be used for designing self-referenced refractive index sensors.

Summary: Phytochemicals play an important role in reducing the risk of chronic diseases. However, current health products marketed as supergrains or superfoods rarely include baked snacks, mainly due to limited understanding of the impact of industrial processes on phytochemicals. This review brings together data on how dehydration processes influence phytochemical retention in baked snacks and discusses the limitations of conventional technologies and barriers to adopting new technologies. Additionally, it explores the potential for a circular economy and a shift in agriculture to enhance the nutritional attributes of crops.

Summary: Raman spectroscopy is a powerful technique for fingerprinting materials and molecules, but fluorescence interference is a common issue. Wavelength-modulated Raman spectroscopy can reduce fluorescence background, allowing clear recording of desired Raman signals. While studying vibrational strong coupling, advantages of the wavelength-modulated Raman approach are found, but results on strong coupling remain inconclusive, calling for further research.

Summary: Two-dimensional semiconducting transition metal dichalcogenides (TMDs) have unique optoelectronic properties, and are often enclosed in a dielectric layer grown with atomic layer deposition (ALD). This study investigates the effects of ALD on the properties of monolayer TMDs, specifically MoS2 and WSe2, by analyzing the changes in photoluminescence and Raman signals. The results show a significant shift and decrease in intensity, which are attributed to chemical doping, strain, and dielectric screening after the ALD. This research highlights the potential of ALD as an alternative method for engineering the doping, strain, and dielectric environment in TMDs for optoelectronics and photonics applications.

Summary: This study re-examines the impact of infrared strong coupling on photoisomerization rates and finds that the variations observed can be attributed to the absorption of ultraviolet radiation in the cavity, rather than strong coupling.

Summary: This paper reports two strategies for realizing hybrid photodetection mechanisms in high-performance broadband photodetectors. These mechanisms can be achieved through the adjustment of the atomically-thin tunneling barrier and the bandgap contrast across the van der Waals heterojunction interfaces. By switching the operation, the hybrid photodetection can be optimized to cover a wide range of wavelengths from ultraviolet to mid-infrared.
