“…Thus, the calculated wavelength sensitivities are 1000, 2000, and 2200 nm/RIU, respectively. The maximum wavelength sensitivity, i.e., 2200 nm/RIU is comparable with previously proposed results [8,12,18,28]. The resolution of the sensor is another important parameter that represents how a small change of analyte RI can be detected by the sensor.…”

Abstract:In this paper, we numerically demonstrate a two-layer circular lattice photonic crystal fiber (PCF) biosensor based on the principle of surface plasmon resonance (SPR). The finite element method (FEM) with circular perfectly matched layer (PML) boundary condition is applied to evaluate the performance of the proposed sensor. A thin gold layer is deposited outside the PCF structure, which acts as the plasmonic material for this design. The sensing layer (analyte) is implemented in the outermost layer, which permits easy and more practical fabrication process compared to analyte is put inside the air holes. It is demonstrated that, at gold layer thickness of 40 nm, the proposed sensor shows maximum sensitivity of 2200 nm/RIU using the wavelength interrogation method in the sensing range between 1.33-1.36. Besides, using an amplitude interrogation method, a maximum sensitivity of 266 RIU −1 and a maximum sensor resolution of 3.75 × 10 −5 RIU are obtained. We also discuss how phase matching points are varied with different fiber parameters. Owing to high sensitivity and simple design, the proposed sensor may find important applications in biochemical and biological analyte detection.

“…Assuming that ∆n a = 0.01, ∆λ min = 0.1, and ∆λ peak = 22 nm, we found the resolution of the proposed sensor to be as high as 4.55 × 10 −5 , which is comparable with [8,12,16,18,28]. Therefore, any small change in analyte RI in the order of 10 −5 can be detected with a high degree of accuracy.…”

This paper proposes a hexagonal photonic crystal fiber (H-PCF) structure with high relative sensitivity for liquid sensing; in which both core and cladding are microstructures. Numerical investigation is carried out by employing the full vectorial finite element method (FEM). The analysis has been done in four stages of the proposed structure. The investigation shows that the proposed structure achieves higher relative sensitivity by increasing the diameter of the innermost ring air holes in the cladding. Moreover, placing a single channel instead of using a group of tiny channels increases the relative sensitivity effectively. Investigating the effects of different parameters, the optimized structure shows significantly higher relative sensitivity with a low confinement loss.

“…Some unique novel properties of PCFs have drawn the attraction of researchers for its more flexibility than conventional optical fibers. Development of regular or irregular PCF structure helps researchers to achieve more efficiency as well as use it in multipurpose like gas sensing [2][3][4][5][6], chemical sensing [7], bio sensing [8], cancer cell detection [9], medical science [10], and temperature sensing [11][12]. Like different structural shape, geometrical parameters of fiber are also responsible to vary guiding properties [13].…”

Abstract.A hybrid structure photonic crystal fiber gas sensor is presented in this paper to detect toxic and colorless gases. The guiding properties of proposed structure have been numerically investigated using finite element method (FEM). From the numerical results sensitivity of the proposed structure is enhanced to 15.67%. The Confinement loss or Leakage loss decreased to 1.12×10-7 by acquainting an octagonal ring of air holes in the outer cladding. The proposed H-PCF can be used in a wider range of wavelength from 0.8µm to 2 µm. The proposed structure has significantly lower confinement losses, higher sensitivity and is more flexible for its simplicity compared with early proposed PCFs.Keywords: Hybrid Photonic Crystal Fiber (H-PCF), Evanescent Field, Gas Sensor, Sensitivity, Finite Element Method and Confinement Loss.
