“…6(a) and 6(b), while analyte RI is changed from 1.33 to 1.40. It can be evident from the figure that the amplitude sensitivity increases gradually with an increase in the analyte RI and reaches the maximum for analyte RI of 1.40 which are 554.9 RIU -1 and 636.5 RIU -1 for x-and y-polarized modes, respectively, which are higher than the results reported in [9,17,24,27,28].…”

“…Actually, the resolution is related to the precision of the measurement, but they are not the same thing, and it can be expressed as [29] According to (4), it is clear that the greater the resonance wavelength shift is, the lower the sensor resolution is, hence, the small amount of change in analyte RI can be detected precisely. The maximum sensor resolution of the proposed design is calculated as 1.72 × 10 -5 RIU and 8.7 × 10 -6 RIU for x-and y-polarized modes, respectively for the analyte RI of 1.40, which is higher than the resolution reported in [18,27,28].…”

“…The reduction of the loss depth and red shift of the resonance wavelength occur with an increase in the gold layer thickness due to the damping effect of the gold layer [27]. The reduction of loss depth results in weak interaction between the evanescent field and the analyte, hence reducing the amplitude sensitivity [17].…”

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.

“…Moreover, the use of the proposed sensor system may be possible for biosensors, especially, using gold nanoparticles for the detection of viruses (cells). [22][23][24][28][29][30] 3 | SIMULATION RESULTS During simulation, the reflected power of the center ring resulted in a shift in the Bragg wavelength of the optical field generated by the grating sensor that can be detected at the add port as shown in Figure 2.

In this study, we propose a model for the dual mode gold grating sensor using a microring conjugate mirror (MCM) and the plasmonic island. The sensor measurement of derived quantity is the change in the Bragg wavelength and electron mobility that can be related to the optical phase‐shift or gold grating mobility changes. The plasmonic island consists of the stacked layers of silicon‐graphene‐gold materials. At the resonant condition, the gold electron mobility is driven by the whispering gallery mode generated by the nonlinear microring resonator. Additionally, the 3D reflection power profile of the grating sensor and target source interaction can be formed by the MCM. By selecting the suitable parameters, it can be arranged to have the four‐wave mixing output, which is the criterion of the 3D output of the MRC. The calculation results have shown that there is a relationship between the change in the electron mobility and Bragg wavelength of ~1.5 × 10−21 cm2 V−1 s−1 (mW)−1 at the λ Bragg of 1.55 μm, where the separation of 1 nm is obtained. The related mathematical formulas are re‐arranged for suitable applications.
