Summary: Utilizing strong light-matter coupling can modify the energy landscapes of excited states of organic semiconductors. This can be achieved by implementing them in optical microcavities, without the need for chemical modification. In this study, the strong coupling of Davydov transitions in polycrystalline pentacene thin films to surface lattice resonances supported by open cavities made of silver nanoparticle arrays was demonstrated. These thin films, together with the open architecture, are more suitable for device applications.

Summary: We studied the interaction between localized and hybridized plasmons in gold nanostars and excitons in J-aggregates, revealing the quality performance of the formed plexciton system in terms of strong coupling parameters. Time-resolved experiments elucidated the observed enhanced spontaneous emission rate in relation to the Purcell effect.

Summary: The vibrational strong coupling of molecules to optical cavities based on plasmonic resonances has been explored recently due to the ability of plasmonic near-fields to provide strong coupling in sub-diffraction limited volumes. This work demonstrates an angle-independent plasmonic nanodisk substrate that overcomes limitations of traditional optical cavities and allows for strong coupling with all molecules on the surface, regardless of molecular orientation. The large linewidths of the plasmon resonance enable simultaneous strong coupling to two orthogonal water vibrational modes, with the Rabi splitting varying as a function of plasmon frequency and strong coupling achieved for a range of diameters.

Summary: The photoluminescence quantum yield of cyanine J-aggregates can increase by an order of magnitude in blend solutions of water and alkylamines at room temperature. Time-resolved photoluminescence studies show an increased exciton lifetime as a result of suppressing non-radiative processes. Small-angle neutron scattering studies suggest the formation of highly emissive J-aggregates requires a sharp water/amine interface and the coexistence of nanoscale-sized water and amine domains.

Summary: This study presents a comprehensive theoretical and numerical investigation on the optical responses of Fabry-Perot cavity-WS2 photonic crystal hybrid structures. The results demonstrate strong coupling between excitons, guided-mode resonances, and F-P modes, and even the possibility of triple mode strong coupling by tuning the spectral overlap. The findings suggest that optical microcavities embedded with TMDC photonic crystals can serve as promising platforms for polariton devices based on multi-mode strong coupling.

Summary: Experimental realization of thin films with significant room-temperature magnetoelectric coupling coefficient α(ME) without an external DC magnetic field has been challenging. Here, large α(ME) of 750 +/- 30 mV Oe(-1) cm(-1) is achieved in multiferroic polymer nanocomposites (MPCs) thin films. The MPCs consist of PMMA-grafted cobalt-ferrite nanoparticles uniformly dispersed in piezoelectric polymer P(VDF-TrFE). Nanoparticle agglomeration is reduced by surface functionalization with PMMA, enabling the uniform dispersion of nanoparticles in submicrometer thin films. This research can promote the development of flexible and printable multiferroic electronic devices for sensing and memory applications.

Summary: We demonstrate the parametric coupling between two modes of a silicon nitride membrane by applying an oscillating voltage to a sharp metal tip near the membrane surface. The modes exchange energy periodically and faster than their free energy decay rate when the voltage oscillation frequency matches the mode frequency difference. This flexible method can be useful for rapid state control and transfer between modes, and is an important step towards parametric spin sensing experiments with membrane resonators.

Summary: This study obtained and analyzed the optical spectra of a semiconductor slab containing a quantum well that acts as a source of magnetoexcitons in the presence of an external dc magnetic field. The researchers discovered a resonant structure in the reflectivity, transmissivity, and absorption spectra, originating from the excitation of electromagnetic modes localized on the semiconductor slab and strongly coupled with the confined magnetoexcitons. Surprisingly, the Rabi splitting was found to be greater for the setup with dielectric gap layers compared to metallic and semiconductor microcavities.

Summary: In this paper, the coherent optical properties of a plasmonic system consisting of metal nanoparticle arrays and a WS2 thin film were investigated. The coupling factor, energy splitting, and temporal dynamics of this coherent coupling phenomenon were quantitatively revealed, and it was found that the exciton behavior of WS2 is modulated by surface lattice resonances. This work may open up new possibilities for the coherent modulation of polariton and plasmon devices.

Summary: Integrating functional oxide-based nanocomposite thin films on Si wafer is a significant progress in the field of electronics and spintronics. By using a buffer layer, the lattice mismatch and potential inter-diffusion between complex oxides and Si are effectively overcome, leading to highly textured growth of the nanocomposite films along the c direction. Magnetic measurements reveal a strong ferromagnetic-antiferromagnetic coupling in the nanocomposite system.
