“…The sensitivity of the PCW slab sensor with smaller holes in the line-defect is reported to be 120 nm/RIU after immersing the structure to deionized water [20]. In this study, by in ltrating only the central row of holes, the sensitivity parameter has reached to 282.4 nm/RIU.…”

“…Buswell et al enhanced the bulk index sensitivity 40% (from 88 nm/RIU to 120 nm/RIU) by placing small size holes in the line--defect [20]. In this study, a much higher improvement of sensitivity (5.3 times) is achieved by selectively in ltrating only the holes in the line-defect (central holes).…”

We present a liquid refractive index sensor based on a photonic crystal waveguide slab structure. Sensing mechanism employed in this study is based on the shift in cut-o wavelength as the lattice holes are selectively in ltrated. Three-dimensional plane-wave expansion and nite-di erence time-domain methods are used to determine the band structure and transmission spectra, respectively. First, the sensitivity of the device is analyzed for the structure where only the rst rows of holes adjacent to the line-defect are in ltrated. In addition, this analysis is repeated for a range of hole diameters. Second, the e ects of in ltrated holes which are placed in the line-defect are investigated. As these in ltrated central holes are introduced, the proposed device exhibits 5.3 times improved sensitivity.

Abstract:A micro structure porous cored octagonal photonic crystal fiber (P-OPCF) has been proposed to sense aqueous analysts (alcohol series) over a wavelength range of 0.80 m to 2.0 m. By implementing a full vectorial finite element method (FEM), the numerical simulation on the proposed O-PCF has been analyzed. Numerical investigation shows that high sensitivity can be gained by changing the structural parameters. The obtained result shows the sensitivities of 66.78%, 67.66%, 68.34%, 68.72%, and 69.09%, and the confinement losses of 2.42×10 10 dB/m, 3.28×10 11 dB/m, 1.21×10 6 dB/m, 4.79×10 10 dB/m, and 4.99×10 9 dB/m at the 1.33 m wavelength for methanol, ethanol, propanol, butanol, and pentanol, respectively can satisfy the condition of much legibility to install an optical system. The effects of the varying core and cladding diameters, pitch distance, operating wavelength, and effective refractive index are also reported here. It reflects that a significant sensitivity and low confinement loss can be achieved by the proposed P-OPCF. The proposed P-OPCF also covers the wavelength band (O+E+S+C+L+U). The investigation also exhibits that the sensitivity increases when the wavelength increases like S O-band

Abstract:In this paper, a two-dimensional photonic crystal (2DPC) based pressure sensor is proposed and designed, and the sensing characteristics such as the sensitivity and dynamic range are analyzed over the range of pressure from 0 GPa to 7 GPa. The sensor is based on 2DPC with the square array of silicon rods surrounded by air. The sensor consists of two photonic crystal quasi waveguides and L3 defect. The L3 defect is placed in between two waveguides and is formed by modifying the radius of three Si rods. It is noticed that through simulation, the resonant wavelength of the sensor is shifted linearly towards the higher wavelength region while increasing the applied pressure level. The achieved sensitivity and dynamic range of the sensor is 2 nm/GPa and 7 Gpa, respectively.
