Abstract: In this paper, we numerically compare the performances of chalcogenide and silica glasses in a surface plasmon resonance sensor. The different glass prisms considered here are fused silica and 2S2G chalcogenide. Further, thin Ag and Au layers are considered as the plasmon-active metal films. The angular interrogation method along with multilayer matrix method has been used to evaluate the sensor's performance in terms of intrinsic sensitivity, which takes both angular shift as well as the angular width of plasmonic curve into account. The adequate conditions are predicted in order to achieve the best possible sensing performance. This comparative study can be very useful to design an optical sensor for chemical and bio-sensing applications in infrared wavelength region due to large operating window of chalcogenide materials.


Keywords: Prism material, Chalcogenide, Surface plasmon resonance, Intrinsic sensitivity, Sensor, Bimetallic
