摘要

This work investigate the sensitivity controlling of the plasmon polaritons resonance at the interface of five levels cesium atom and silver metal. The sensitivity of the plasmon polaritons is highly influences by the driving fields parameters. The peak value of sensitivity is found to 3000 \(\theta /RIU\) against the control field detuning ( \(\Delta _{3}\) = −1 \(\Gamma\) ) as well as the probe and control fields detunings (resonance point of probe field detuning \(\Delta _{p}\) = 0 \(\Gamma\) and \(\Delta _{3}\) = 2 \(\Gamma\) ). The minimum value of sensitivity is reported to 1100 \(\theta /RIU\) against control field detuning ( \(\Delta _{2}\) = −1.5 \(\Gamma\) ). This results plays a crucial role in advancing data storage systems and plasma-based technologies.
