Summary: In this paper, a novel waveguide structure capable of supporting highly confined spoof surface plasmonic (SSP) mode with lower propagation loss is proposed. By analyzing the 2D and 3D structures of the waveguide, it is found that a subwavelength cross-sectional size waveguiding structure with high field confinement and low propagation loss can be achieved if the gap region is properly designed.

Summary: We study the simultaneous narrowband and broadband light absorption enhancement of monolayer graphene on a metallic substrate with a periodic array of small holes. The absorption peaks of graphene are proven to stem from the hybrid modes of delocalized surface plasmon polaritons propagating on the substrate surface and localized magnetic plasmons confined within individual holes. The positions, maxima, and bandwidths of the absorption peaks can be tuned through changing the hole array period. The maximum absorption values at the narrowband and broadband peaks can reach up to 65% and 85%, respectively. The bandwidths of the absorption peaks can be conveniently adjusted, with the narrowband peak reduced to several nanometers and the broadband peak expanded to tens of nanometers.

Summary: In this research, a high-contrast narrow-band optical diode with a significant forward-to-backward ratio in the near-infrared region is presented. The design utilizes a dielectric-based diffraction grating waveguide on a thin silver layer to excite two surface plasmon modes simultaneously, achieving high contrast transmission. The spectral response of the proposed device is verified using rigorous coupled-wave analysis and finite difference time domain.

Summary: A plasmonic grating with three functions is proposed and numerically demonstrated, allowing for the excitation of different types of SPPs such as Cherenkov SPPs wake, nondiffracting SPPs Bessel beam, and focusing SPPs field by modulating the excitation light with linear gradient, symmetrical, or spherical phase. This approach enables dynamic manipulation of the features of these functions without requiring extra fabrication, thus reducing costs in practical applications.

Summary: A double-layer metal superlens was designed to improve subwavelength imaging ability. The transmission properties of the imaging system were accurately interpreted using waveguide mode theory. By amplifying high spatial frequency evanescent waves and diminishing low spatial frequency evanescent waves, a flat and broad optical transfer function was achieved, improving the subwavelength imaging performance.

Summary: This article investigates the dynamic modulation of optical skyrmions by changing the field symmetry and adding chirality. The study reveals that field symmetry controls the transformation between skyrmions and merons, while material chirality regulates the degree of twist in the fields and spins, and governs the skyrmionic transition. The enantioselective twist of skyrmions and merons arises from the chirality-induced splitting of the hyperboloid in momentum space. The research enriches the portfolio of optical quasiparticles and deepens our understanding of light-matter interaction, paving the way for applications such as chiral sensing, optical tweezing, and topological phase transitions in quantum matter.

Summary: This study establishes a new scheme for realizing highly miniaturized couplers to efficiently excite on-chip photonic devices. By utilizing both resonant and Pancharatnam-Berry mechanisms, the meta-device can couple circularly polarized light to a surface plasmon and focus it onto a target on-chip device. Experimental results demonstrate the high efficiency of this scheme in exciting on-chip waveguides and dual-waveguide systems.

Summary: This work reports the observation of 2D longitudinal aberrated wavefields by mapping the intensity distributions of surface plasmon polaritons (SPPs) propagating on a metal/air interface. The SPP beam orientation can be adjusted to mimic aberrated beams, showing Seidel terms such as defocus, spherical, coma, and tilt aberrations. This approach provides a visual and rapid examination of the longitudinal evolution of aberrated beams compared to more complicated post-processing reconstructions.

Summary: Asymmetric optical transmission is crucial in many optical systems. In this study, a dielectric-metal metasurface is introduced to achieve high-performance asymmetric transmission for linearly polarized light in the near-infrared region. The metasurface supports a forward transmittance peak and a backward transmittance dip at the same wavelength of 922 nm, significantly enhancing operation bandwidth and contrast ratio.

Summary: This study overcomes the diffraction limit of optical microscopy in resolving subwavelength nanoslits by measuring the full Stokes parameters of the scattered field. The state of polarization of the scattered light strongly depends on the slit width for subwavelength nanoslits, providing a new far-field optical technique to determine their width accurately.
