▎ 摘　　要

The dynamic nature of radiation damping is exploited in a fluoride fiber-based plasmonic sensor in terms of variable temperature (T) and Ag layer thickness (d(m)) at certain near-infrared wavelengths. The optimum point of radiation damping, which is stimulated by the presence of a graphene monolayer and its dynamic dispersive and thermo-optic properties as per Kubo formulation, causes extremely huge enhancement in sensor's performance (analyzed in terms of its figure of merit, i.e., FOM). The simulation indicates that at lambda = 1550 nm, the optimum radiation damping is achieved at d(m) = 35 nmand T = 322.7Kleading to a peak FOM value of 27,086 RIU-1. At. = 1310 nm, the peak FOM is 16,736.65 RIU-1 for d(m) = 35.4 nm and T = 315.6 K. The above peak FOM values are significantly greater than those presently available with plasmonic sensors.
