Summary: This study deeply analyzes the influence of the roughness of shallow or deep metallic diffraction gratings on the propagation of surface plasmon mode along the metallic-air interface. It is found that the scattering losses lead to a spectral or angular broadening of the surface plasmon resonance (SPR) and a shift of the resonance wavelength and coupling angle. These effects need to be overcome when using such structures, especially deep ones, as SPR-based sensors.

Summary: In this study, single-crystalline aluminum nanowires with high stability were fabricated using a superplastic nanomolding technique. These nanowires exhibit multimode waveguiding, efficient beam splitting based on polarization, and durable thermal optical modulation, making them suitable for nanophotonic routers, splitters, and information encryptors. This technique can also be extended to other metals, enhancing the development of functional nanophotonic devices and integrated optical chips.

Summary: Gold-coated tilted fiber Bragg gratings (TFBGs) have been extensively studied for biosensing applications, with a more sensitive demodulation method based on the intersection of the upper and lower envelopes of TFBG spectra being reported in this paper. This method has been successfully applied in detecting HER2 proteins, and practical improvements such as superimposing a uniform FBG and implementing a micro-fluidic system have been made to enhance the sensing platform for practical applications.

Summary: Metal-semiconductor nanostructures are widely used in photodetection, photocatalysis, and photovoltaics. In photodetection, the resistance typically decreases with the generation of charge carriers upon illumination, but an opposite response, an increase in resistance, is observed in interconnected metal-semiconductor gratings. This study presents a fabrication method using wrinkle structuring and oblique angle material deposition to create photoresistors with large-area periodic structures and cracks that serve as connections for two-point contact measurements. It is also found that an additional deposition of an amorphous titania layer further enhances the current reduction on photoexcitation.

Summary: In this study, silver nanowires were embedded in a polymer waveguide doped with Rhodamine 6 G. The waveguides were constructed using electron beam lithography. The results showed a significant gain in the polymer waveguide and an increase in the intensity of scattered plasmons by pumping Rhodamine at the end of the nanowire.

Summary: A meta-grating-based SPR sensor was studied for its self-referencing operation in the near-infrared region using spectral interrogation technique. The introduction of a high RI dielectric material, SiON film, between the dielectric metasurface and metal layer enabled self-referencing in the sensor. The proposed sensor showed optimized geometrical parameters and achieved high sensitivity up to 1150 nm/RIU with a high FOM of 442.31 RIU(-1).

Summary: A deep metal grating allows for simultaneous excitation of two counterpropagating surface plasmon modes using diffraction orders. The resulting angular reflection spectra exhibit three interleaved zeros and maxima. This new surface plasmon resonance sensing scheme shows high sensitivity and a limit of detection of 2 x 10-7 refractive index unit (RIU) was achieved.

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.
