Combustible or harmful gasses noticeable all around are adequate to decimating a geographical region of bringing about a flame, explosion, and venomous exposure. In this paper, a highly sensitive gas sensor based on slotted-core photonic crystal fiber has been presented which can be used as a gas sensor. The guiding properties of the proposed PCF are numerically investigated by employing finite element method (FEM). The Proposed PCF contains slotted core and a hexagonal cladding where the geometrical parameters are varied to optimized. Simulation result reveals that the proposed PCF shows a high relative sensitivity of 48.26%, the high birefringence of 2.17×10-2 and a lower confinement loss of 1.26×10 -5 dB/m. Effective area, Beat length, Splice loss, V-parameter are also reported in this paper.
