Abstract.  Modeling of a fused silica (SiO2) glass prism-based plasmonic structure comprising of indium oxide (In2O3)–zirconium dioxide (ZrO2)–silver (Ag)–zinc oxide (ZnO) intermediate layers showing enhancement in sensitivity and figure-of-merit (FOM) in visible and infrared regime has been reported in this paper. Performance of the proposed plasmonic structure has been demonstrated in terms of sensitivity, half width (HW), detection accuracy (DA), and FOM parameters in visible (632.8 nm) and infrared (1200 nm) wavelength of light. High sensitivity of fused silica glass material, In2O3, ZnO films along with high DA and high FOM of Ag and inclusion of ZrO2 as an oxidation protective layer in between In2O3 and Ag have been the most exciting and advantageous features of our proposed structure. Simulated sensitivity values of our proposed structure were found to be 73.8  deg/RIU at 632.8 nm wavelength and it was found enhanced to 109.6  deg/RIU at 1200 nm wavelength and simulated FOM values were also found enhanced from 23.3544  RIU1 at 632.8 nm to 62.6285  RIU1 at 1200 nm wavelength for change in sensing layer refractive indices from 1.30 RIU to 1.35 RIU.
