Summary: This study investigates the mode-mode interaction mechanism in photonic molecules composed of degenerate-mode cavity and single-mode cavity, revealing that direct coupling can lift mode degeneracy and lead to mode splitting. The introduction of direct coupling results in single Fano resonance and dual EIT-like effects in the double-cavity photonic molecule structure, with improved filtering bandwidth and peak transmission.

Summary: This work investigates the properties and alignment effects of controllable gold nanorods in magnetic fields. Cationic polyethyleneimine-functionalized superparamagnetic nanoparticles are deposited on the surface of gold nanorods, and the magnetic alignment of nanorods is achieved by magnetic dipolar interactions. The experimental results demonstrate the potential for rotational manipulation of these nanorods in rotating magnetic fields. This research has important implications for further developments in nanophotonics applications.

Summary: This study focuses on the light-assisted temperature control in a complex nanoparticle network. By analyzing the light-induced thermal behavior, the boundary and quantitative effects of multiple scattering and thermal accumulation are determined using the Green's function approach. The results show that the more compact the nanoparticle ensemble is, the stronger the multiple scattering effect and the weaker the thermal accumulation effect. Furthermore, the polarization-dependent distribution is only observed in the compact ensemble.

Summary: In this study, we theoretically investigate the enhancement of ultra-broadband near-infrared absorption in monolayer graphene by using a multiple-resonator approach. We demonstrate that by carefully designing the nanostructure with multiple one-dimensional nanogrooves on metal surfaces, the absorption efficiency of graphene can be significantly improved to over 60% in a wide near-infrared wavelength range. This work is of interest for the development of photoelectric devices, such as infrared photodetectors.

Summary: This study conducted a detailed spectral analysis of the radiation absorption and scattering behaviors of metasurfaces through photonic simulations. It was found that the absorbance and scattering cross-sections exhibit a ratio of 1 at the absorption peak spectral position. By increasing the absorption through optical materials, the total absorption efficiency can be controlled, leading to near-perfect absorption and emission of thermal radiation.

Summary: By creating an all-dielectric periodic array between Si nanopillars and SiO2 nanopillars, plasmon lattice resonances (PLR) were achieved with a line-width as small as 3.3 nm. The diameter and height of Si nanopillars, the period of the array, and the height of SiO2 nanopillars were found to have significant impacts on the formation of PLR. This work extends the application of PLR in nanophotonics.

Summary: Metallic nanostructures acting as optical nanoantennas can significantly enhance the photoluminescence of nearby emitters. The proposed solid-state ultraviolet emitter based on a thin film of zinc oxide coupled with an array of aluminum nanoparticles demonstrates enhanced near band-edge emission compared to bare zinc oxide. Surface lattice resonances are shown to be more efficient for luminescence enhancement in zinc oxide compared to localized surface plasmon resonances.
