“…The silicon core is designed in PCF to broaden the filtering bandwidth by reducing the area of the effective film [24,25]. In addition, the D-type PCF not only improves the sensitivity of the sensor [26], but also improves the performance of the filter [27].…”

In this paper, a D-type grating-modified broadband photonic crystal fiber polarization filter based on surface plasmon resonance is proposed. The asymmetric design of D-type photonic crystal fiber is helpful to achieve single-mode polarization filtering, and grating can increase the coupling between the core mode and the SPP mode and thus increase the constraint loss. From our simulation results, it can be seen that the applicable bandwidth range can easily reach 1 μm. At the communication wavelength of 1750 nm, the calculated constraint losses of x-polarized and y-polarized core modes are 4.2526 dB cm−1 and 1491.8 dB cm−1, respectively, and the crosstalk is up to 1292 dB. The proposed grating-modified of photonic crystal fiber has achieved good filtering effect in the near-infrared band, and even extended to the mid-infrared band.

Surface plasmon resonance (SPR) is a key technique in developing sensor platforms for clinical diagnostics, drug discovery, food quality, and environmental monitoring applications. While prism‐coupled (Kretschmann) SPR remains a “gold‐standard” for laboratory work‐flows due to easier fabrication, handling and high through put, other configurations such as grating‐coupled SPR (GC‐SPR) and wave‐guide mode SPR are yet to fulfil their technology potential. This work evaluates the technical aspects influencing the performance of GC‐SPR and reviews recent progress in the fabrication of such platforms. In principle, the GC‐SPR involves the illumination of the plasmonic metal film with periodic gratings to excite the surface plasmons (SP) via diffraction‐based phase matching. The real performance of the GC‐SPR is, however, heavily influenced by the topography of the grating structures produced via top‐down lithography techniques. This review discusses latest in approaches to achieve consistent plasmonic gratings with uniform features and periodicity over a large scale and explores the choice of plasmon‐active and substrate material for enhanced performance. The review also provides insights into the different GC‐SPR measurement configurations and highlights on opportunities with their potential applications as biosensors with translational capabilities.
