“…So these two parameters depend on the plasmonic material thickness. The loss curve for different plasmonic thickness at analyte RI=1.38 is shown in Fig.4.The decrease in the loss depth is due to the damping effect of the gold [10]. Therefore, less energy from fundamental core mode is transferred to the plasmonic mode when compared with gold thickness of the lower value.…”

This paper is a demonstration for the design of photonic crystal fiber biosensor which is based on the phenomenon of surface plasmon resonance. The plasmonic coating covers the outer layer of the Photonic Crystal fiber to ease the fabrication process, we choose Gold. To quantitatively measure the represented design, we utilize a technique called as the Finite element method (FEM). To accomplish the sensitivities of 4300nm/RIU and 408.468 RIU-1 we apply the methodologies of wavelength and amplitude interrogation models. This design yielded a resolution of 2.33×10-5 respectively. A fluctuation from 1.33 to 1.39 in the analyte refractive index can be identified and measured by this design. The sensing range of the design is wide and may also be used in biological detection.

With the continuous development of optical fiber sensing technology, the photonic crystal fiber (PCF) sensor based on surface plasmon resonance (SPR) excited by the LP 0;1 mode has attracted extensive attention. In this work, an SPR PCF excited by the HE 1;1 mode is designed and the various structural parameters are optimized from the perspective of the wavelength sensitivity. The phase matching, mode field distribution, wavelength sensitivity, amplitude sensitivity, structural parameter sensitivity, and figure of merit (FOM) of the PCF-SPR sensor are systematically and comprehensively analyzed numerical by the finite element method and the characteristics are compared to those of representative PCF sensors reported in recent years. The highest wavelength sensitivity of the PCF-SPR sensor is 25;800 nm∕RIU, resolution is 3.87 × 10 −6 RIU, and FOM is 289.83 RIU −1 . The excellent sensing properties suggest that the sensor has immense potential in petroleum logging, geological exploration, and other applications.

A surface plasmon resonance (SPR) sensor based on dual-layered air hole shaped photonic crystal fiber (PCF) is proposed to realize the simultaneous measurement of refractive index (RI). The plasma materials silver (Ag) and titanium dioxide (TiO 2 ) were sequentially coated on the outer surface of PCF to obtain enhanced sensing properties. By carefully adjusting the geometrical parameters, the simulation results show a maximum wavelength sensitivity of 72000 nm/RIU for analyte refractive indices ranging from 1.26 to 1.365, which realizes the high-sensitivity sensing in the visible to near-infrared optical band. Moreover, the sensor attains a maximum figure of merit (FOM) of 229 and RI resolution of 1.29  10 -6 . This work shows great potential for real-time, affordable, and accurate measurement in biomedical, biological and organic chemical domains.
