Abstract: (2579 Views)
In this paper, a highly sensitive and tunable nano-sensor based on metal-dielectric-metal structure is presented. Actually, the goal is to propose a nano-sensor by using perfect absorbing. Sensitivity and tunability of all optical sensors are important parameters in their design, which are investigated by using numerical and analytical methods. Results show that the proposed sensor has Max sensitivity of 693/8 nm/RIU with refractive index change of Δn=0/05, and Figure of Merit (FoM) equal to 9/8. Also, the proposed nano-scale sensor can operate as a light propagation controlling with slow and fast light. By using of silver metal in the sensor structure, the fast and slow light coefficient is obtained of 220 and 70, respectively.
