Abstract: (541 Views)
In this paper, a fiber optic based glucose sensor is designed and simulated. The structure of the biosensor consists of a single-mode optical fiber, with D shaped cross section, and coated by metal. When gold or silver used as metal layer, Plasmon resonant frequencies will be in the visible spectrum. Proteins and other biomolecules usually are measured in the IR region. To move plasmon resonant frequency to IR region, Indium Tin Oxside (ITO) is used such as metal layer. By introducing two graphene layer on the both side of ITO, performance of the sensor has been improved. The results of FEM simulation shows the sensitivity is 6500 nm / RIU.
