Summary: This study demonstrates the control of polarization state in rare-earth ions doped upconversion nanoparticles (UCNPs) at the nanoscale and single-particle level by constructing angularly anisotropic plasmonic local-field distributions in gold nanorods (Au NRs) antennae. The enhanced upconversion luminescence (UCL) of UCNP tailored by plasmonic Au NRs nanoantennae exhibits linear polarization. The findings have significance in the study of optical polarization control and its applications in optoelectronic devices.

Summary: This paper presents a method to achieve strongly enhanced linearly polarized emission by integrating monolayers of transition metal dichalcogenides (TMDCs) with a designed plasmonic nanocavity. The results show that plasmon-exciton coupling leads to the formation of plasmon-exciton polaritons, which contribute to a significantly higher linear polarization at room temperature.

Summary: Anisotropy is important in various material systems, but creating and controlling it has been a challenge. Polarization-addressed anisotropy is attractive due to its controllability, simplicity, and accuracy, but only a few material systems can achieve it. In this study, a polarization-dependent anisotropic etching system made of Au@oligomer core-shell nanoparticles was established. The etching process is faster along the polarization direction, resulting in shape anisotropy of the particles. This system has advantages of high selectivity, controllability, and versatility, opening up new possibilities for on-chip nanofabrication.

Summary: The optical properties of nanoparticle assemblies are influenced by the unique characteristics of their building blocks and spatial organization, leading to emergent phenomena. A fast, materials agnostic method has been developed to simulate the optical response of large nanoparticle assemblies with structural and compositional complexity. This method overcomes the limitations of conventional electromagnetic simulations and achieves rapid and accurate convergence for complex configurations, enabling the design of complex and hierarchically structured assemblies with desired optical characteristics.

Summary: In this paper, electrically driven plasmonic nanoantennas were investigated as a local source of optical signals for on-chip data processing. By using scanning tunnel microscopy-induced light emission, the optoelectronic properties of single gold nanodiscs were probed and the electromagnetic field distribution near plasmonic structures was studied with high spatial resolution. The results showed a nonuniform distribution of electromagnetic near-fields and a direct correlation between nanoantenna optical states and current-voltage characteristics.

Summary: Water scarcity is a major concern for human sustainability and ecosystem preservation. Seawater desalination, particularly membrane distillation, has emerged as a sustainable solution. However, temperature polarization in membrane distillation leads to a significant reduction in water flux. Plasmonic nanostructures in membranes and the efficient conversion of light into heat offer potential prospects for enhancing solar-driven membrane distillation.

Summary: With the increasing demand for energy storage technology, developing battery systems with higher energy density is urgent. In this study, Si@Cu nanoparticles with core-shell structures enclosed in a 3D CNTs network were synthesized to overcome the limitations of Si, such as large volume variation and low conductivity. The synergistic effects of Cu coating and the 3D CNTs network resulted in improved electrochemical performance and capacity retention. Si@Cu/CNTs exhibited a high capacity and favorable rate capability, making it a promising modification strategy for Si materials.

Summary: To address issues of volume expansion, poor silicon conductivity, and capacity decay, a rational design of the silicon negative electrode is crucial. In this study, a graphene confined Si@Cu core-shell structure (Si@Cu@rGO) was developed as an integrated anode. The copper shell on the silicon nanosurface enhances electronic conductivity, while the flexibility of the copper shell and graphene helps maintain electrode morphology and contact. Additionally, the graphene cladding prevents nanoparticle aggregation and provides space for silicon expansion, while the three-dimensional redox graphene layer accelerates reaction kinetics. The Si@Cu@rGO exhibited satisfactory electrochemical performance, with a specific capacity of 2243.1 mAh g(-1) after 70 cycles in the rate performance test. (c) 2023 Elsevier B.V.

Summary: Narrow bandwidth Fano-like spectrum with tunable slope ratio, stable intensity extremums, and high extinction ratio was achieved by coupling HE mode components with whispering gallery mode. The theory presented calculations to analyze the spectra profiles including the slope ratio and extremums of the transmission. In the experiment, modified positive and negative slope ratios were achieved with extremums varying less than 10%. This configuration has wide applications in optical sensing, optical switching, and dispersion control.

Summary: Time metamaterials, including anisotropic photonic time crystals, have shown promising potential for wave manipulation. In this study, we investigate the unique wave dynamics of an anisotropic photonic time crystal formed by a periodically changing anisotropic medium. We demonstrate that a stationary charge embedded in the time crystal emits radiation, contrary to isotropic photonic time crystals, and its momentum distribution is controlled by the time crystal's band structure. This work expands the functionalities of time metamaterials and opens up new possibilities for radiation generation and control, with implications in classical and quantum applications.

Summary: We investigated the laser emission of a polymer-cholesteric liquid crystal superstructure with coexisting opposite chiralities. By filling a right-handed polymeric scaffold with a left-handed cholesteric liquid crystal material, the superstructure exhibited two photonic band gaps corresponding to right- and left-circularly polarized light. Dual-wavelength lasing with orthogonal circular polarizations was achieved in this single-layer structure by adding a suitable dye. The left-circularly polarized laser emission was thermally tunable, while the right-circularly polarized emission was relatively stable. Our design has potential applications in various fields of photonics and display technology due to its simplicity and tunability characteristics.

Summary: In this study, efficient second harmonic generation (SHG) was demonstrated from a merged bound state in the continuum (BIC) based on a lithium niobate (LN) freestanding metasurface. The merged BIC effectively reduces radiative loss and enhances the quality factor (Q factor). The achieved conversion efficiency of 1% under a 5 degrees incident angle and 2 kW/cm2 input intensity surpasses the performances of other nanostructures supported by traditional isolated BICs. This work offers a promising way to enhance light-matter interactions at nanoscales and provides a feasible idea for designing ultracompact SHG light sources.

Summary: We study the chirality of field at exceptional points (EPs) in an optical whispering gallery mode (WGM) microcavity, and find a locally imperfect or locally perfect chirality of eigenmodes at the EPs. The generally local and imperfect chirality tends to be globally perfect with decreasing scattering effect induced by nanoscatterers. By modeling the dynamic multiple-scattering process of azimuthally propagating modes (APMs), we provide explanations for the above counterintuitive phenomena of imperfect or perfect chirality.
