摘要

The sensing of surface plasmon resonance is controlled at the boundary between a four-level dielectric material and graphene. This study demonstrates the ability to adjust the sensitivity of the surface plasmon polaritons by varying system parameters and driving fields. Additionally, the sensitivity of SPPs is influenced by both the detuning of the probe field and the Rabi frequency of the control field. The peak value of sensitivity observed for SPPs is 700 degrees/RIU, achieved through specific detuning of the probe field and Rabi frequency of the control field. Conversely, the minimum sensitivity recorded is 250 degrees/RIU, which is linked to the phase of the control field. These results highlight potential applications in fields such as biosensing, nanophotonics, data storage, waveguiding, and solar energy harvesting.
