“…Over the last 20 years, photonic crystal fibers (PCFs) have garnered significant research interest due to their superior optical characteristics, which are essential in various emerging technological fields. 87,99,100 Integrating air holes within the fiber structure broadens the spectrum of waveguide parameters, facilitating distinct guiding mechanisms. PCFs are broadly categorized into two types based on their guiding mechanisms: (i) index-guiding PCFs, which operate through modified TIR, 101 similar to traditional fibers, and (ii) photonic bandgap fibers (PBG)-PCFs, which confine light within a low-index solid, hollow core, 102 allowing only specific light wavelengths to pass through.…”

Optical biosensors exhibit immense potential, offering extraordinary possibilities for biosensing due to their high sensitivity, reusability, and ultrafast sensing capabilities. This review provides a concise overview of optical biosensors, encompassing various platforms, operational mechanisms, and underlying physics, and it summarizes recent advancements in the field. Special attention is given to plasmonic biosensors and metasurface-based biosensors, emphasizing their significant performance in bioassays and, thus, their increasing attraction in biosensing research, positioning them as excellent candidates for lab-on-chip and point-of-care devices. For plasmonic biosensors, we emphasize surface plasmon resonance (SPR) and its subcategories, along with localized surface plasmon resonance (LSPR) devices and surface enhance Raman spectroscopy (SERS), highlighting their ability to perform diverse bioassays. Additionally, we discuss recently emerged metasurface-based biosensors. Toward the conclusion of this review, we address current challenges, opportunities, and prospects in optical biosensing. Considering the advancements and advantages presented by optical biosensors, it is foreseeable that they will become a robust and widespread platform for early disease diagnostics.

“…The free electrons on the metal surface have the ability to absorb incident light. As a result, a surface plasmon wave (SPW) is produced [13]. When stimulated at the SPR wavelength, the conspicuous loss peak shows extremely great sensitivity to the liquid analytes [14].…”

“…When the PCF's phase-matching requirement between the fundamental and surface plasmon-polariton (SPP) modes is met, the SPR is frequently employed in optical fiber detection [15]. To advance PCF sensing technology, several SPR-based PCF refractive index sensor types have been investigated within the last 20 years [12][13][14][15][16][17][18]. The detection of biological and biomolecular analytes [4], bioengineering [9], biochemistry [6], and bioimaging [17] are only a few applications for the SPR phenomenon.…”

In this paper, we present a novel method for building a plasmonic photonic crystal fiber (PCF) sensor with simplified features to identify unknown analytes. Using the special parameters of plasmonic PCFs, the suggested sensor increases the sensitivity and specificity of target analyte detection. We provide a streamlined design approach that reduces manufacturing complexity without sacrificing reliable performance, opening up the sensor to new useful applications. We show the optimal structure parameters for optimizing sensitivity using the finite element method in the COMSOL environment. The suggested configuration attained strong spectral sensitivity throughout an extensive range of the analyte's refractive indices. Furthermore, a perfect linear connection was established between the analyte's refractive index and the resonant wavelength, qualifying the sensor for usage across the whole range of the analyte's refractive indices.

“…Meng designed a D-shaped PCF-SPR sensor with double loss peaks, exhibiting a high sensitivity of 18 900 nm/RIU in the sensing range of 1.35-1.38 [15]. From the sensors aforementioned, most PCF-SPR sensors are mainly applied to sensing of RIs above 1.33 [16][17][18]. While the applications for low RI detection are relatively rare, which could be used to detect analytes with RIs below 1.30, such as liquid CO 2 , medical oxygen, and sevoflurane [19].…”

A novel concave-shaped photonic crystal fiber sensor with double loss peaks based on surface plasmon resonance is proposed, whose properties are investigated by the finite element method. Gold can be utilized to generate excitation between the core mode and surface plasmon polariton mode. The simulation results indicate that in the wavelength range of 1.2 to 2.2 μm, the proposed sensor could detect the refractive index (RI) in the range of 1.18–1.30, the wavelength sensitivity of the primary loss peak could reach up to 18 000 nm/RIU and the corresponding resolution is 5.56 × 10−6 RIU in the RI range from 1.26 to 1.27. In addition, the double loss peaks could improve the detection accuracy, and the trough wavelength variation range is small, indicating that the proposed sensor is relatively stable, which improves the practicability of the sensor. This work could have a wide application value in the detection of medical testing, biomolecules, and organic chemistry.
