Sensitivity of the Surface Plasmon Polariton Waves at the Interface of Metal and Dielectric Medium Using Doppler Broadening Effect

The angular interrogation of sensitivity of the surface plasmon polariton waves (SPPs) is investigated at the interface under the effect of Doppler broadening dielectric medium and silver metal using prism geometry. A useful manipulation over the sensitivity of SPPs is obtained with Doppler broadening effect and parameters of the probe and control fields. The maximum sensitivity is investigated to 3000 deg/RIU with control field detuning, while the manimum sensitivity is reported to 300 deg/RIU with doppler width. The modified result of sensitivity of this manuscript shows potential applications in radiations guiding, photovoltaic devices, and solar cells devices.
