Design and Performance Analysis of a D–shaped PCF and Surface Plasmon Resonance Based Glucose Sensor

Abstract

Now a day's diabetes is a common disease all over the world. The levels of glucose in our body increase when our body is unable to convert glucose to energy because of insufficient insulin. To maintain the acceptable level of glucose, we need some advice from the doctor. It's also required regular basis check-up the glucose level. To detect the glucose of human blood, we propose a D-shaped PCF glucose sensor where gold use as the metallic layer and glucose is the sensing layer. COMSOL Multiphysics 5.0a has used as the simulation tool to design our proposed sensor. Simulation result shows, the plasmonic D-shaped PCF can achieve wavelength sensitivity of 3000nm/RIU and amplitude sensitivity of 241 RIU <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> with a corresponding sensor resolution of 3.341 X 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> RIU.
