Improving field localization and figure-of-merit value in plasmonic structures via path-interference effect
Özet
We present here an ultra-intense field localization at both on-resonant and off-resonant wave-lengths via path interference effect in nanoscale Au Bow-tie structure with single molecule coupling. First, the physics behind the Au Bow-tie with single molecule interaction is explained. Then, path-interference effect is obtained through analysis and some simulations performed with 3D Maxwell Solver (MNPBEM) in MATLAB. The coupling yields ultra-narrow resonances due to path-interference, which are very sensitive to changes into refractive index of surrounding medium. The figure-of-merit for the proposed structures is also calculated and it is demonstrated that much higher values can be obtained compared to conventional plasmonic sensors.
