Highly Sensitive Photonic Crystal Fiber based Sensor for Sensing Nitrous Oxide (N2O) and Benzene (C6H6) Gas Present in the Atmosphere

Abstract

Photonic crystals have some unique properties if any optical fiber depends on those fundamentals it is meant to be a PCF. It is designed by using the three major elements such as core, cladding, and the PML. Here, the detection Nitrous Oxide (N2O) and Benzene (C6H6) Gas present in the atmosphere is done by designing a highly sensitive Photonic Crystal Fiber based sensor. There are many ozone depleting elements in that one of the major harm is due to (N2O) gas and it even causes many health defects to living organisms such as depression, hypoxia, psychosis, damages immune system, and loss of memory. Basically, there is a presence of (C6H6) gas in the atmosphere these elements react with the chemical compounds creating smog which breaks down at some point and then the collision between rain and snow happens resulting in contamination of water and soil. It also results in harming the human beings by creating problems such as increasing heart rate, unconsciousness, level of RBC gets decreased, and damaging the bone marrow. Due to all these reasons, at the present scenario it is very much needed to sense the Nitrous Oxide (N2O) and Benzene (C6H6) Gas at atmospheric level. The highly sensitive proposed model is designed by using the COMSOL Multiphysics software by obtaining an accurate and high performing output. The simulation results are calculated by using the final element method which results in the relative sensitivity of 99.384%, 99.937% and 9.56 × 10−11 dB/m, 0dB/m loss of confinement at the wavelength of λ = 1μm, 0.20μm for N2O and C6H6 Gas. According to the above results it is proved that the proposed gas sensor is very simple with high rate of performance and accuracy.
