Monitoring of CS2 Gas with Very High Accuracy using Photonic Crystal Fiber

This work expresses a circular center core fiber based gas sensor for noticing carbon disulphide (CS2). In this paper, the entire reenactment has finished by COMSOL software by (FEM). The rectangular center based sensor is working for observing the gases with a high affectability differentiation to strong and circular center PCF sensors. Distinctive mathematical boundaries of this plan, for example, air opening, center material, cladding material and Perfectly Matched Layer (PML) have been dramatically investigated to make the plan more compelling. This plan furnishes the overall sensitivity of 99.53% with a confinement loss of 0.002 dB/m at λ= 1.8 μm intuition of CS2. The lower compelling region based rectangular gas sensor can keep a lot of light in the center and results the best presentation. The result gives the sensor being a fitting contender for noticing CS2 gas in the climate precisely.
