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

“…Some identical properties are seen like as nonlinearity [1,2], high birefringence [3,4], high sensitivity [5,6], low confinement loss [7,8], improved effective area, and endlessly single mode [9][10][11]. For these reasons, PCF has drawn a great attraction among researchers.…”

“…This structure is used to avoid the propagation of electromagnetic wave in a certain frequency band, which is called photonic bandgap [1]. This properties and other capabilities like high flexibility design in the nanometer scale and integration with photodetector and laser, have turned photonic crystals to one of the important fields in the nano-scale researches [2][3][4][5]. One of the impressive factors for the photonic crystal lattice is the refractive index [6].…”

Abstract:We design an ultra-compact water temperature sensor by using the photonic crystal technology on the InP substrate at the 1.55-µm wavelength window. The photonic crystal consists of rods in a hexagonal lattice and a polymethyl methacrylate (PMMA) background. By using the plane wave expansion (PWE) method, the lattice constant and radius of rods are obtained, 520 nm and 80.6 nm, respectively. With a nanocavity placed in the waveguide, a resonance peak is observed at the 1.55-µm wavelength window. Any change of the water temperature inside the nanocavity results in the shift of the resonance wavelength. Our simulations show a shift of about 11 nm for a temperature change of 22.5 ℃. The resonance wavelength has a linear relation with the water temperature.
