“…Linearity presents the ratio between the transducing parameter and measurand, which can reflect the sensing stability of the entire system during the detection. A high linearity response of regression line indicates a good sensor [50]. For an RI-based FOSP system, the linearity can be plotted between the loss resonance wavelength and analyte RI.…”

The survey focuses on the most significant contributions in the field of fiber optic plasmonic sensors (FOPS) in recent years. FOPSs are plasmonic sensor-based fiber optic probes that use an optical field to measure the biological agents. Owing to their high sensitivity, high resolution, and low cost, FOPS turn out to be potential alternatives to conventional biological fiber optic sensors. FOPS use optical transduction mechanisms to enhance sensitivity and resolution. The optical transduction mechanisms of FOPS with different geometrical structures and the photonic properties of the geometries are discussed in detail. The studies of optical properties with a combination of suitable materials for testing the biosamples allow for diagnosing diseases in the medical field.

“…In other structures, sensors with a silver–graphene layer could prevent silver from being oxidized [ 11 , 12 ]. The silver film [ 13 ] and gold film [ 14 ] coated on the outer layer of the PCF have high sensitivities. Three-holed PCF coated with an auxiliary dielectric layer and gold film makes analyte filling easy [ 15 ].…”

The characteristics of the dual-core photonic crystal fiber (PCF) sensor are studied using the finite element method (FEM), and the structure is improved according to the numerical simulation results. The results show that whether or not the four large air holes far away from the geometry center of the PCF are filled with analyte has no influence on the wavelength sensitivity of the sensor which means those holes can be replaced by small air holes. The wavelength sensitivity can be tuned by adjusting the sizes of the other large air holes which are as for liquid holes. The dynamic detection range of the refractive index (RI) is from 1.33 to 1.51. In particular, high linearity is obtained in the range of 1.44 to 1.51. The sensitivity is as high as 6021 nm/RIU when the liquid holes are the smallest. When liquid holes are tangential with the envelope of first layer air holes, the wavelength sensitivity is 4028 nm/RIU, and the coefficient of determination (R2) is 0.99822 when the RI of the analyte varies from 1.44 to 1.51 which shows that high sensitivity and good linearity are both obtained.

“…In the same fashion, side-polished hexagonal structured D-shaped PCF-SPR biosensor was demonstrated by Tiesheng et al [10] with the excellent value of wavelength sensitivity (21 700 nm/RIU) without considering amplitude sensitivity which is a very important term for characterizing the SPR sensor. Moreover, highly sensitive SPR biosensors were reported that focused on the high spectral sensitivity rather than considering amplitude sensitivity [11,12].…”

A numerical analysis on dual core photonic crystal fiber (DC-PCF) based surface plasmon resonance (SPR) refractive index sensor is presented. The guiding parameters and required sensing performances are examined with finite element method (FEM) based software under MATLAB environment. According to simulation, it is warranted that the proposed refractive index sensor offers the maximum amplitude sensitivity of 554.9 refractive index unit (RIU −1 ) and 636.5 RIU −1 with the maximum wavelength sensitivity of 5800 nm/RIU and 11 500 nm/RIU, and the sensor resolutions of 1.72 × 10 −5 RIU and 8.7 × 10 −6 RIU, at analyte refractive index (RI) of 1.40 for x-and y-polarized modes, respectively. As the sensing performance in different wavelength ranges is quite high, the proposed sensor can be used in simultaneous detection for different wavelength ranges. Therefore, the proposed device is of a suitable platform for detecting biological, chemical, biochemical, and organic chemical analytes.
