A Review Paper on Performance Quantification of Refractive Index Sensors

We have witnessed a lot of advancements in sensors after the introduction of optical fiber technology. Over the past few decades, researchers have shown great interest in a new technology, named Surface Plasmon Resonance (SPR) which uses the light-metal interaction involved at a metal-dielectric interface. SPR has emerged as a great detection technique due to its flexibility, high sensitivity and multiplexing capabilities. This detection method has given superior results across various categories of research. This technology is used for fast, precise and accurate measurement of diverse physical, chemical and biochemical parameters. Optical resonance techniques based refractive index (RI) sensors are receiving a lot of attention because of the need to design simple, low-cost, high-throughput detection technologies for a number of applications. The parameters which quantify the performance of the SPR technique for sensing purposes have been reviewed in this paper with review of phenomena of SPR technology. The content of the review article may be of great significance for the researchers in the field of fiber-optic SPR sensors.
