Photonic crystal fiber sensor structure with vertical and horizontal cladding for the detection of hazardous gases

The gases which are generated in the industrial areas are very harm. Knowingly or unknowing the people who work near this hazardous area are affected lot and now it is the right time to detect these harmful gases in an efficient manner. In order to sense these hazardous gases a type of sensor that should sense these gases in an efficient manner, one such sensor is Photonic Crystal Fiber (PCF). The different gases such as SO₃, Sicl₄, CCl₄, C₁₀H₁₆, Sncl₄ are analyzed with the same Vertical PCF (V-PCF) and Horizontal PCF (H-PCF) gas sensor which was designed earlier for the detection of SO₂ gas in an efficient manner. By maintaining the same design parameters different gases are sensed and compared with the SO₂ gas outputs for the wavelength range of 0.8 μm to 1 μm. A sensitivity of 65.86% and 71.80% at 1 μm for C₁₀H₁₆, SnCl₄, and other gases may be detected with the optimized V-PCF and H-PCF gas sensor. These gases are harmful and it will cause serious issues to the human beings. The different parameters such as sensitivity, effective mode area and attenuation are analyzed for different gases.
