Exploitation of Slotted Multilayer Coatings for the Enhancement of Light Transmission and Sensitivity Through Surface Plasmon Resonance Waveguide
We propose a metal slotted dielectric waveguide with a high refractive index material in which surface plasmon can propagate. By studying several symmetrical metal dielectric metal structures we have also analysed that slot waveguide geometry also shows many intriguing properties that are not shown in the single interface metal dielectric with the use of high refractive index material. The surface plasmon resonances of slot MDM waveguide are studied using finite difference time domain simulations. The slot MDM waveguide geometry not only exhibit high index sensitivity (≈200 RIU–1) but also shows higher transmission (≈10%). We have also investigated the geometry with different dielectric materials (Air, Silicon-di-Oxide). The transmission obtained is in the given order Au–Si–Air–Au > Au–Si–Au > Au–Si–SiO2–Au for slot MDM structures.
