N2 - This study proposes a chemical sensor based on bi-core photonic crystal fiber (BC-PCF) in the terahertz (THz) frequency regime with a novel construction that has two solid cores separated apart by a vertical elliptical hole filled with various chemicals such as ethanol, benzene, and water. Because of the ability that BC-PCF has to transmit light across all wavelengths, the solid core architecture is chosen for this sensor. The proposed sensor is able to attain extraordinarily high sensitivity because of the unique arrangement of circular and elliptical holes, which offers a substantial advantage over existing structures. The principle on which the proposed chemical sensor operates involves the coupling of modes between the two fiber cores. The finite element method (FEM) based COMSOL Multiphysics software has been used to comprehensively analyse and simulate the sensor's performance. Remarkably, the sensor is able to achieve a high sensitivity of 725833.34 nm/RIU with a fiber length of 0.2 meter. The use of this BC-PCF chemical sensor in the industrial sector is mainly aimed at efficiently identifying and detecting toxic chemicals.
