“…Because of its ability to control light in hollow bodies, the loss of blockage is very low and the contact of light is increased, resulting in increased fiber sensitivity [2]. A number of reported works [3][4][5][6][7][8][9][10][11][12][13][14][15][16] have been developed to investigate the performance of optical sensors based on PCF. In several applications, PCF is used, such as gas detection [3][4], chemical detection [5][6], pressure detection [7], biomedical and temperature sensing, etc.…”

A vertical photonic crystal fiber (V-PCF) and horizontal PCF (H-PCF) are designed for the detection of sulfur dioxide (SO2) in this paper. A demanding numerical investigation is carried out in a wider range of wavelengths from 0.8 μm to 1μm. SO2 is a major contributor to air pollution, which is responsible for asthma and cancer. The optical parameters are analyzed by using the Finite Element Method (FEM) which consumes a completely circular isotropic Perfectly Matched Layer (PML). The designed V-PCF sensor test is performed with different PML radius values, different elliptical constants for the inner cladding, the outer cladding layer, and the core. The higher relative sensitivity of 59.34% makes this proposed V-PCF a good design for SO2 detection.

“…The growths of photonic crystal fibers (PCFs) with their significant optical properties have confirmed the prospective benefits of optical fibers in chemical and biological sensing [1] [2] [3]. The outstanding characteristics of these micro structured fibers such as small size, freedom of design, and relative compatibility make them stand out for sensing applications [4] [5] [6]. Where in conventional fibers, designing is not so easy, core size is limited, material selec- tion is tough etc.…”

This paper presents the investigation of relative sensitivity profile of Alcohol through Photonic Crystal fiber at different temperature. Here, 15%, 40%, 60%, 75% of Ethyl Alcohol-water mixture is inserted through the core of Photonic crystal fiber at temperature like 20˚C, 25˚C and 30˚C. COMSOL Multiphysics is used as simulation software and the simulation process is done at wavelength range 600 nm to 1600 nm. From this work, the relative sensitivity is obtained approximately 44, 44.59, 44.85, 45 in percentage at temperature 20˚C, 42, 44.2, 44.8, 44.9 in percentage at temperature 25˚C, and 42, 43.8, 44.5, 44.85 in percentage at temperature 30˚C for 15%, 40%, 60%, 75% of Ethyl Alcohol-water mixture at wavelength 1500 nm respectively. Again, higher sensitivity is achieved when this sensor is operated at lower temperature.

“…Recently, several PCF designs for high birefringent and broadband dispersion compensating have been reported [26][27][28][29], but it requires a very sophisticated manufacturing process to realize the reported PCFs because their cross sections are not based on the conventional lattice structure and all air holes are not circular.…”

We propose a highly birefringent and dispersion compensating photonic crystal fiber based on a double line defect core. Using a finite element method (FEM) with a perfectly matched layer (PML), it is demonstrated that it is possible to obtain broadband large negative dispersion of about -400 to -427 ps/(nm.km) covering all optical communication bands (from O to U band) and to achieve the dispersion coefficient of -425 ps/(nm.km) at 1.55µm. In addition, the highest birefringence of the proposed PCF at 1.55 μm is 1.92 × 10 -2 and the value of birefringence from the wavelength of 1.26 to 1.8 μm (covering O to U bands) is about 1.8 × 10 -2 to 1.92 × 10. It is confirmed that from the simulation results, the confinement loss of the proposed PCF is always less than 10 -3 dB/km at 1.55 μm with seven fiber rings of air holes in the cladding.
