The Photonic Crystal Fiber (PCF) is used as a chemical sensor to detect the hydrogen sulfide (H2S) released from the industries. The cladding area in which the air gaps are arranged as in the shape called hexagon, and the micro porous air gaps are present in the inner core area. The required solution which has to be analyze is placed in the air gaps of the inner core area. In this proposed method the simulation of PCF is done with COMSOL Multiphysics software by using the full vectorial Finite Element Method (FEM) which provides relatively high sensitivity, high effective area and extremely low confinement loss. The proposed idea has been accomplished with relatively optimum level sensitivity at 2.5 µm and minimum confinement loss of 1.34918 E-09 dB/m at 5 µm pitch. This proposed structure will be elite commitment for recognizing the H2S gas precisely.
