“…Thus, for a large range of RI analytes, there are two different types of SPRs, namely, the 'dielectric-like' and the 'plasmonlike', respectively due to different resonance wavelengths. Further, they are also known as 'incomplete coupling' and 'complete coupling' [12] [30] [31] [32]. We note that the phase matching conditions for them are found to be different.…”

In this paper, we design a 6-fold D-shaped photonic crystal fibre sensor based on the surface plasmon resonance (SPR). The coupling between fundamental core mode and three surface plasmonic modes which have different electric filed distributions for analytes of various refractive indices. We observe two different types of SPRs, namely, 'dielectric like' resonance with low-loss peak and 'plasmon like' resonance with high-loss peak, by analyzing the electric field distribution of the fibre modes. Further, we discuss the influence of the secondary SPR over the main SPR which is directly related to the detection performance of the proposed sensor. In order to mitigate the adverse effect of the sub-peak of the secondary SPR on the sensor's dynamic sensing range (DSR), we reduce the thickness of analyte's binding layer from 1500 nm to 500 nm. Thus, DSR can be extended to 44.4% from 1.33-1.41 to 1.33-1.45 at the cost of a reduced maximum sensitivity from 7900 nm/RIU to 5300 nm/RIU. Owning to the simple structure design of the proposed sensor, we envisage that this highly sensitive D-shaped PCF-SPR sensor could be developed as a versatile and competitive instrument with a large and flexible refractive index detection range.

“…More complex structures have also been proposed. A triangular lattice and four large-size channels based on surface plasmon resonance was investigated in [218]. In such a sensor, two gold wires obtained by chemical reaction are filled in two air holes between the upper and lower channels.…”

Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic arrangement of microstructured holes located in the fiber’s cladding. Light confinement is achieved by means of either index-guiding, or the photonic bandgap effect in a low-index core. Ever since PCFs were first demonstrated in 1995, their special characteristics, such as potentially high birefringence, very small or high nonlinearity, low propagation losses, and controllable dispersion parameters, have rendered them unique for many applications, such as sensors, high-power pulse transmission, and biomedical studies. When the holes of PCFs are filled with solids, liquids or gases, unprecedented opportunities for applications emerge. These include, but are not limited in, supercontinuum generation, propulsion of atoms through a hollow fiber core, fiber-loaded Bose–Einstein condensates, as well as enhanced sensing and measurement devices. For this reason, infiltrated PCF have been the focus of intensive research in recent years. In this review, the fundamentals and fabrication of PCF infiltrated with different materials are discussed. In addition, potential applications of infiltrated PCF sensors are reviewed, identifying the challenges and limitations to scale up and commercialize this novel technology.

“…The bimetallic layer also assists in increasing wavelength sensitivity and sensing range. Until now, various PCF structures have been proposed—internal metal-coated [19], external metal-coated [20], side-polished [21], D shape [22], modified D shape [23], open channel [24], and slotted [25]—to improve the sensing response. Rifat et al proposed a D -shaped Au-TiO 2 bimetallic coated plasmonic sensor [7], which shows the highest loss of 23.18 dB/cm, an average wavelength sensitivity of 9800 nm/RIU, and a resolution of 2.2 × 10 − 6 RIU.…”

In this paper, a low-loss, spiral lattice photonic crystal fiber (PCF)-based plasmonic biosensor is proposed for its application in detecting various biomolecules (i.e., sugar, protein, DNA, and mRNA) and biochemicals (i.e., serum and urine). Plasmonic material gold (Au) is employed externally to efficiently generate surface plasmon resonance (SPR) in the outer surface of the PCF. A thin layer of titanium oxide (TiO2) is also introduced, which assists in adhering the Au layer to the silica fiber. The sensing performance is investigated using a mode solver based on the finite element method (FEM). Simulation results show a maximum wavelength sensitivity of 23,000 nm/RIU for a bio-samples refractive index (RI) detection range of 1.32–1.40. This sensor also exhibits a very low confinement loss of 0.22 and 2.87 dB/cm for the analyte at 1.32 and 1.40 RI, respectively. Because of the ultra-low propagation loss, the proposed sensor can be fabricated within several centimeters, which reduces the complexity related to splicing, and so on.
