Evanescent Field Absorption Based Fiber Optic Sensor Using Chalcogenide Glasses for Biological Tissues Detection

An evanescent field based fiber optic sensor is proposed using ternary chalcogenide glasses under diffuse source illumination for straight fiber for detection of biological tissues. The field distribution within the core region and evanescent field beyond it has been shown pictorially. The simulation is performed in near infrared region for three liver tissues, normal liver tissue (N), Non-cancerous metastatic tissue (NMET) and non-cancerous hepatocellular carcinoma tissue (NHCC). Interrogation of absorption coefficient and transmitted power has been performed. The effect of variation in core diameter and wavelength on sensitivity of the samples have been studied to have high sensitivity.
