Paper Abstract

A multilayered fiber SPR sensor is studied with graphene multilayers for ethanol detection. The sensor design variants (graphene mono-, bi-, tri-, and quadra-layer) are simulated and analyzed at 1310 nm and 1550 nm wavelengths. The dynamic radiation damping in terms of variable temperature and Ag layer thickness is enforced on the sensor variants to lead to possible sensing performance enhancement. At an optimum radiation damping (ORD) condition (317.8 K temperature and 35.1 nm thick Ag layer at 1550 nm wavelength), the figure of merit (FOM) of the fiber (ZBLAN core and NaF clad) SPR sensor with graphene monolayer has the potential to reach to an ultrahigh magnitude of 27164.89 RIU-1 . The proposed sensor can be an important milestone in developing highly sensitive and accurate fiber optic chemical sensors.
