Summary: This study demonstrates theoretically the active role of two-dimensional metallic photonic crystals (PhCs) as hybrid plasmonic-photonic lattices in light-matter interaction. By coupling optical waveguides with periodically arranged metallic nanodisks, the formation of waveguide-plasmon polaritons is achieved, showing strong coupling between waveguide-plasmon modes and excitons in WS2 at room temperature. Control over mode composition and coupling strength between polaritons by tuning lattice geometry reveals the LSPR-mediated energy transfer process, contributing to fundamental understanding and potential practical applications.

Summary: This paper proposes a method and codes for fast computation of complex dispersion relations in three-dimensional photonic crystals. The method converts the eigenproblem to a nonlinear equation equivalent to the zero-determinant condition, which can be solved iteratively using fixed-point iteration or rational approximation method. Additional mathematical elements, such as fast-converging continued-fraction expansion and efficient accounting for rectangular geometry, are included. The method enables realistic three-dimensional computations on a typical laptop computer.

Summary: The optical Tamm state is an electromagnetic mode that exists at the interface between a periodic dielectric structure and a metal layer. This article presents a detailed study on the existence of optical Tamm states in opal-like three-dimensional photonic crystal structures and reveals the presence of a hybrid Tamm-PhC bandedge state between a corrugated metal layer and 3D-PhC. The nature of the hybrid Tamm-PhC bandedge states strongly depends on the thickness of the metal layer, and no mode hybridization was observed at the interface between flat metal and 3D-PhC.

Summary: In this study, the progress of nanoengineering on noble metals and the extreme nonlinear optics within nanometric volumes are explored. Plasmonic nanostructures are found to offer a unique route for enhancing high-order harmonic generation and other nonlinear optical progress. The researchers demonstrated a strong third harmonic emission in zinc oxide microbelts through a strong localization of electromagnetic field caused by localized surface plasmon resonances. The intensity of third-harmonic generation was enhanced significantly in a composite of microbelts and Au nanoparticles, compared to the bare microbelts. Additionally, the polarization characteristics of the third-harmonic generation in the same system were improved significantly.

Summary: This study demonstrates the near-infrared light-driven reversible and dynamic photonic bandgap modulation of soft photonic crystal through the integration of core-shell upconversion nanoparticles and a novel molecular photoswitch. The intensity ratio of UV/vis luminescence emitted by the UCNPs can be controlled by changing the excitation power, leading to red-shift and blue-shift of the photonic reflection. This work provides new insights into the fabrication of 3D photonic nanostructures with tailorable functionalities for soft-matter photonics and integrated communication technologies.

Summary: In this paper, a unified finite difference framework is proposed to efficiently compute band structures of three-dimensional linear non-dispersive isotropic photonic crystals with any of the 14 Bravais lattice structures. The difficulties arising from high multiplicity of zero eigenvalues have been overcome by redefining a suitable orthogonal coordinate system, reformulating the Bloch condition, and identifying the hierarchical companion matrix structure of the resulting discretized partial derivative operators.

Summary: Aqueous supercapacitors are considered promising for commercial energy storage devices due to their safety, low cost, and environmental friendliness. However, the challenge of achieving both long electrode lifespan and qualified energy-storage property has hindered their practical application. In this study, an electrode-electrolyte integrated optimization strategy is developed to meet real-life device requirements. By optimizing the nanomorphology and surface chemistry of the tungsten oxide anode, along with the design of a hybrid electrolyte, record-breaking durability and stable operation under extreme conditions are achieved. These results demonstrate the possibility of replacing commercial organic energy storage devices with aqueous counterparts for various daily applications.

Summary: Traditional OAM generation devices are bulky and limited to creating OAM with one specific topological charge. This study demonstrates a tunable multi-topological charge OAM generator based on an ultrathin integrable graphene metalens. Different topological charges can be designed on different focal planes and dynamically changed by stretching the graphene metalens. This design method paves the way for miniaturization and integration of OAM beam-type photonic devices.

Summary: A novel metal-free 2D/2D van der Waals heterojunction was successfully constructed by integrating a two-dimensional COF with ketoenamine linkage and defective hexagonal boron nitride. The presence of VDW heterojunction and introduced defects facilitated charge carriers separation and provided more reactive sites. The resulting heterojunction exhibited excellent solar energy catalytic activity for water splitting, surpassing the performance of pristine COF and other metal-free-based photocatalysts reported to date.

Summary: In this investigation, two-dimensional (2D) layered perovskite single crystals with a vertical gradient band gap were successfully synthesized using a solid-state halide diffusion process. The crystal and morphology of the synthesized crystals remained intact, as confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) measurements. The formation of a vertical gradient band gap was observed through transmittance and photoluminescence (PL) spectra, and was attributed to the gradient halide distribution achieved via halide intermixing. The synthesized mixed halide crystals exhibited high stability and enhanced carrier transport, making them suitable for various applications that require vertical carrier transport. The halide diffusion behavior was found to be different from the previously proposed layer-by-layer diffusion model in exfoliated crystals.

Summary: The study demonstrates the observation of chiral surface lattice resonances (SLRs) that are formed by the coupling of chiral toroidal electric dipole (TED) moment and Rayleigh anomaly (RA) mode. By engineering the rotational symmetry of a propeller metasurface, the electric dipole (electric quadrupolar) chiral SLRs evolve into TED-associated chiral SLRs. The excitation amplitude of the TED moment can be tailored by controlling the stereo twisted height of the propeller and the spin of the incident light.

Summary: The power-sensitive photo-thermal tuning (PTT) behavior of graphene oxide (GO) integrated on the top surface of silicon nitride (SiN) waveguides is experimentally investigated. The thresholds for reversible and permanent GO reduction are measured for SiN waveguide coating with monolayer GO. Three reduction stages are identified based on the reversibility of the reduction process. The study confirms that the PTT is primarily determined by the average input power, regardless of the type of laser used.

Summary: Graphene oxide (GO) films integrated on silicon nitride (Si3N4) waveguides through a solution-based method enhance the spectral broadening and self-phase modulation (SPM) effect. The GO-coated waveguides show significantly improved nonlinear performance compared to the uncoated waveguide, resulting in a broadening factor of up to 3.4 and an improvement in the waveguide nonlinear parameter by a factor of up to 18.4. The high Kerr nonlinearity of GO contributes to the enhancement of SPM in Si3N4 waveguides.
