Summary: This study investigates the optical spin textures from high-k mode polaritons on the surface of silica-silver multilayer hyperbolic metamaterials. The results show that the spin texture changes with an increase in overall thickness, and the size and width of the spin angular momentum are relatively small. These findings could facilitate new applications of hyperbolic metamaterials.

Summary: Topological photonics, with the ability to manipulate light using topological phases, is gaining importance. However, due to the limitations of tunable materials, the use of topological phases in terahertz devices is limited. This study demonstrates a topological phase transition in the terahertz bands by integrating Dirac semi-metal with topological photonic crystal. The proposed structure achieves absorption enhancement by designing a one-dimensional topological edge state, providing topological protection to the entire BDS-photonic crystal heterostructure.

Summary: The lateral Casimir force acting on a 50 nm particle near hyperbolic metamaterial can be enhanced nearly four times compared to that near SiC bulk. This enhancement is caused by the coupling between the resonance mode excited by nanoparticles and the hyperbolic mode supported by hyperbolic metamaterial, providing an efficient method to enhance the interaction of nanoscale objects.

Summary: This paper examines the features of generating two types of surface plasmon-polaritons (SPPs) in optical anisotropic hyperbolic metamaterials formed by a periodic lattice of metal nanocylinders embedded in a dielectric matrix. The dependencies of group velocity and penetration depth of the generated plasmon-polaritons on filling ratio are established and analyzed. Surface plasmon-polaritons generation at the interface of hyperbolic metamaterials is analytically calculated and discussed based on the effective medium theory.

Summary: The study investigates the optical properties of metallic lamellar gratings with sub-wavelength period as a function of groove depth and width. Anomalies are observed under p-polarized illumination due to the excitation of surface plasmon polaritons (SPPs) and their interaction with plasmonic and photonic modes. The propagation constant of SPPs is affected by the presence of corrugations, with new resonances appearing for grooves deeper than half a wavelength.

Summary: In O-and C-band optical communications, Ge is a promising material for detecting optical signals that are encoded into electrical signals. This study investigates 2D periodic Ge metasurfaces that support optically induced electric dipole and magnetic dipole lattice resonances. By overlapping Mie resonances and electric dipole lattice resonances, the researchers realize the resonant lattice Kerker effect and achieve narrowband absorption. The absorptance of the Ge nanoantenna arrays increases 6-fold compared to that of the unpatterned Ge films. Additionally, the photocurrent in Ge metasurface photodetectors increases by approximately 5 times compared with that in plane Ge film photodetectors due to the interaction of these strong near-fields with semiconductors and the further transformation of the optical energy into electricity.

Summary: Periodic nanoparticle arrays have the ability to achieve narrow resonances and tune the resonance position. Multipole decomposition is commonly used to study the interaction of electromagnetic waves with these arrays. However, the validity and accuracy of multipole decomposition near lattice resonances have not been examined. This study demonstrates the applicability of exact multipole decomposition and shows that a small number of multipoles are sufficient to accurately represent the results around lattice resonances.

Summary: Resonant elements are crucial for tailoring the radiation and scattering properties of devices like antennas and functional material platforms. In this study, a simple resonator composed of a dielectric cylinder and an impedance surface is shown to support multiple scattering states. By carefully adjusting its geometry, the resonator can enhance and direct scattering, or suppress scattering to create anapole states. A prototype of the resonator using water as the dielectric and a metallic tube with slits as the impedance surface has been tested at microwave frequencies, demonstrating its flexibility in achieving different scattering responses. This resonator design has significant implications for antenna design and functional material platforms in various frequency domains, including THz and optical frequencies using high-permittivity dielectrics and graphene/nano-particle surfaces.

Summary: The rise of photonics is driven by the need for miniaturization and faster communications, with the promise of high-speed and low-heat light circuits. Near-zero-index materials have attracted attention due to their unique electromagnetic properties, including electric field enhancement and extraordinary transmission in photonic waveguides. In such materials, light propagates with constant phase, showing promise for quantum photonics where information is preserved instead of degraded by the environment. However, realizing these properties remains challenging due to the specific geometries required by the effective medium theory.

Summary: We studied how periodic lattices influence the optical characteristics of silicon and titanium nanoparticle arrays. Our approach involved calculations for finite-size arrays as well as lattice sums for infinite arrays. Our model showed that the convergence to the infinite-lattice limit is faster for broad resonances and that a higher number of nanoparticles is needed for convergence. We also observed that lattice resonances related to higher diffraction orders reach the infinite-array limit more quickly. This research highlights the advantages of using a periodic arrangement of lossy nanoparticles in enhancing the response of transition metals.

Summary: In this work, we report on the design of a layered hybrid plasmonic-dielectric metasurface that facilitates strong mode coupling and the formation of bound states in the continuum (BIC), resulting in resonances with a high quality factor. We demonstrate the possibility of controlling Fano resonances and tuning Rabi splitting using the nanoantenna dimensions. We also experimentally demonstrate the generalized Kerker effect in a binary arrangement of silicon nanodisks, which allows for the tuning of the collective modes and creates new photonic functionalities and improved sensing capabilities.

Summary: Localized plasmonic resonances in isolated nanoparticles are weak, but collective resonances emerge when nanoparticles are arranged in a periodic lattice. This study investigates lattice resonances in nanoantenna arrays made of lossy materials, such as Ti, W, and Ge, and explores practical scenarios in laboratory measurements and nanofabrication processes. The lattice resonances can be tuned for various applications, including sensing, by changing the refractive index of substrate and superstrate materials and considering different surrounding environments.

Summary: Direct simulations demonstrate that materials with low refractive index have superior efficiency in third harmonic generation compared to epsilon-near-zero (ENZ) materials, and they naturally satisfy phase-matching conditions. Silicon-based photonic crystals can effectively generate third harmonic waves, providing a simplified approach to on-chip linear and nonlinear circuitry and reducing potential sources of losses by unifying the production chain with the same material, such as silicon.

Summary: Optical sensors are efficient tools used to detect various types of analytes. High-contrast gratings (HCGs) are nanoscale devices that exhibit sharp optical resonances and can be used to detect biomarkers. Among different HCG structures, pedestal HCGs have higher bulk refractive index sensitivity, while half-buried HCGs have higher surface sensitivity. Both types of HCGs were used for optical biosensing of the cardiac biomarker myoglobin, and the half-buried HCGs showed slightly lower limit of detection compared to pedestal HCGs.
