Abstract
A samarium doped chalcogenide with chemical composition of Se95Te5Sm0.25 fiber core-based surface plasmon resonance (SPR) has been investigated to detect the Tuberculosis having refractive index in the range of 1.343 to 1.351 RIU. Wavelength interrogation is used for analysis purpose. Sensor is designed using Se95Te5Sm0.25 fiber core- NaF clad, gold (Au), graphene and Tuberculosis sample in the wavelength () range of 400-1400 nm. Sensor design involves optimization of metal layer thickness, incident angle of light, core-clad combination to obtain the high-performance parameter. Transmitted power is calculated considering the n umber of reflections using transfer matrix method (TMM). Performance is analyzed in terms of figure of merit (FOM), sensitivity and detection limit. Results indicate that graphene plays significant role to obtain the significant values of performance parameter. Tuberculosis can be detected sensitivity and FOM of values 4600 nm/RIU and 75 RIU-1 with proposed sensor structure.
