Summary: In this work, high-performance surface plasmonic sensors using gold nanostructures and Bragg photonic structures are presented. The hybrid Tamm-plasmon mode, resulting from the Fano coupling between higher order Tatum plasmon states and Bloch-wave surface plasmon polariton on the gold nanoslit array, demonstrates high surface sensitivity and resonant quality. The experimental results show that the hybrid mode has significantly higher sensitivity and better signal-to-noise ratios in biomolecular interaction measurement.

Summary: This letter presents a novel dual-polarized endfire antenna that operates in Ka-band and is fully printed. The antenna utilizes a fish-bone-shaped structure for horizontal polarization (HP) and a mushroom-shaped structure for vertical polarization (VP) to support two orthogonally polarized surface wave modes. By tapering the structures, the antenna achieves a smooth transition between the waveguide and free space, resulting in high gain radiation and a large bandwidth. The measured results demonstrate peak realized gains of 16.9 dBi for HP and 16.0 dBi for VP, with a 3 dB gain bandwidth of 36.3% for HP and 24.4% for VP. Additionally, the antenna is thin (1.5 mm), compact (5 mm), and lightweight (1.1 g), making it a suitable replacement for dielectric rod antennas.

Summary: In this study, a novel strategy is proposed to manipulate the switching and slow wave features of spoof surface plasmon polaritons (SPPs) based on plasmon-induced transparency (PIT) spectral responses. The strategy involves loading a combined module of split square-ring resonators and electric-LC resonators into the SPP waveguide to achieve a high modulation contrast in SPP transmission at the PIT peak frequency.

Summary: The study demonstrates control over the spatial and temporal properties of surface plasmon polaritons (SPPs) launched from nanohole arrays in silver, showing that SPPs launched from multiple arrays can interfere at defined spatial positions to form an all-SPP periodic nano-optical grating that evolves as the SPPs propagate. The spatio-temporal characteristics of the optical grating can be tuned through various nanohole array parameters, and the temporal interference of SPPs with different central wavelengths can be tailored through multiperiodic arrays (MPAs) consisting of arrays with different pitches placed adjacent to one another. Temporal interference serves as an encoded signal, where frequency components can be controlled by array properties.

Summary: This paper presents a new micro/nanostructure co-hot embossing technique for the integration of gold-capped nanostructures as localized surface plasmon resonance (SPR) sensors into a microfluidic channel. The advantage of this technique is that it eliminates the need for alignment between the SPR sensors and the microfluidic channel during bonding. The integrated SPR sensor and microfluidic channel were characterized, and the sensitivity of the SPR sensor to refractive index was determined using different concentrations of glycerol solutions. The SPR sensor was also used for quantifying latent membrane protein (LMP-1) by modifying anti-LMP-1 on its surface, and a calibration curve was created using different concentrations of LMP-1 samples.

Summary: The study focuses on the polaritonic bandstructure of a 2D atomic lattice coupled to a surface plasmon polariton mode in the single excitation regime. By using a computational technique based on Dirichlet-to-Neumann map, a 2D atomic lattice is designed using only two-level atoms with an isolated flat polaritonic band where the group velocity for the modes approach zero across the Brillouin zone. Such a system could be utilized for slowing, storing, and manipulating single photons in a 2D geometry.

Summary: Plasmonics utilizes surface plasmon polaritons (SPPs) which have strong subwavelength field confinement and enhancement, making them promising for on-chip integrated circuits. However, the weak confinement of SPPs and immature near-field technology present challenges for terahertz frequency devices. In this study, a highly confined SPP mode (spoof SPP) is achieved through structured metal surfaces and gradient index lenses are constructed to regulate terahertz waves, enabling further miniaturization and compactness of THz devices.

Summary: A scalar-superposition metasurface is proposed to achieve precise placement of a quantum emitter and tailor the single-photon emission to a desired polarization. The far-field interference of scattered fields from unit nanostructures can be simplified as a scalar-superposition process, making the emission polarization state insensitive to the phase or position of the quantum emitter. The high placement accuracy and robustness of this metasurface, along with its ability to tailor the polarization of multiple single-photon emission spots, provide new possibilities for quantum nanophotonic devices.
