Coherent manipulation of the surface plasmon resonance sensing at the dielectric-graphene interface under Cross-Kerr nonlinearity effect

Sensitivity of surface plasmon polaritons (SPPs) resonance sensing is coherently controlled and modified at the dielectric medium and graphene interface under the cross Kerr nonlinear fluctuation of the dielectric function. The useful control over the sensitivity of the SPPs by control and Kerr fields is reported. The angular interrogation of sensitivity of the SPPs under the Kerr nonlinearity effect is written as $d\theta /d{n}_d^k$. The sensitivity of the SPPs depends on the driving fields parameters such as control and probe fields detuning and control field Rabi frequency as well as decay rate. The sensitivity is a function of probe field detuning, the maximum value of sensitivity of the SPPs is reported to be 3000 deg/RIU with probe field detuning. Whereas the minimum sensitivity is investigated to be 400 deg/RIU with probe fields detunings. The reported results in this manuscript is useful applications in data storage, solar cell, sensor devices and plasmonster technology.
