Coherent manipulation of intensity interrogation of sensitivity of the surface plasmon polariton waves at the dielectric and silver metal interface

Abstract

In this manuscript, Intensity interrogation of sensitivity of the surface plasmon polariton waves (SPPs) is coherently manipulated, at the interface of four‐level dielectric medium and silver metal using prism geometry. Sensitivity of SPPs with respect to refractive index is written as . A useful control in sensitivity is reported with probe and control fields detuning, Rabi frequency and decay rate. Sensitivity is a function of probe field detuning and control field Rabi frequency. The maximum sensitivity is reported to with probe field detuning and control field Rabi frequency, while minimum sensitivity is investigated to with control field phase and control field Rabi frequency. The sensitivity in this manuscript shows useful application in biosensor and photovoltaic devices.
