Abstract
In this paper, D-type single-core fiber optic sensors and dual-core sensors based on surface plasmon resonance are devised with the purpose of comparatively exploring the characteristics of the single- and dual-core models. There is a plane that is thrown out on the surface of the fiber, and we coat this appearance with a layer of silver (Ag), rotating a cyclic distribution of air holes arranged around the PCF core’s perimeter. Three strategically positioned apertures beneath the silver film create two leakage windows. This not only avoids the outward diffusion of the energy of the Y-polarized (Y-POL) core modes, but also facilitates the coupling of Y-POL core modes to the silver film via the leakage windows.…
