Abstract

The review summarizes numerical technique employed simulations of optical fiber plasmonic sensors (OFPS) based on fiber types, probe geometry, metal-dielectric film, and nanostructures. The recent progress in nano-optics has developed susceptible and label-free optical devices by using SPR/LSPR techniques of the thin metal film and nanostructures. The survey focuses on the contribution of numerical analysis based on highly reliant OFPS, incorporating metal layers, strips, nanoparticles, nanowires, metamaterials, along with other new materials and components. Subsequently, the article compares the sensing performance of various sensing structures and analyses the result with applications, which have been published in the last few years. Finally, we examined some conclusions and perspectives and hoped this review might provide adequate directives to researchers/students willing to take up these areas for their future endeavours.
