Photonic crystal fiber sensor based on sensing ring for different blood components: Design and analysis

This article proposed solid core PCF with sensing ring for different blood component detection. Analytical validation of proposed sensor has been done by using FEM numerical technique in term of relative sensitivity and confinement loss. In this PCF design, sensing liquid filled into uniform circular ring and evanescent field interact with sensing liquid for better light matter interaction. This proposed PCF sensor design overcome some experimental challenge such as leakage of light and sensing analyte loss during the displacement of sensing probe. This proposed inner circular channel overcome the drawback of external channel PCF probe. This uniform circular sensing ring around the core overcome the losses and support better evanescent field matter interaction for sensing application.
