A V-shaped ultra-sensitive localized Surface Plasmon Resonance based Biochemical sensor

Abstract

PCF-SPR distinguishing joins the upsides of PCF development and plasmonic to decisively control the short-lived field and light expansion properties in single or multimode courses of action. In terms of SPR-based PCF sensor testing, several investigators have already shown excellence. They also suggested excellent designs with a high sensitivity to amplitude in recent years. The problem for design, though, is that most designs are sensitive to high losses or have low susceptibility and low losses. And the most critical thing is that the prototypes are dynamic to reach high sensitivity. In the simple design we were successful, we tried to eliminate these limitations and achieve great sensibility with a low loss. This research illustrates multiple parametric study based on surface plasmon resonance (SPR) of a slightly gold-coated photonic crystal fiber (PCF). In verifying sensing accuracy, the proposed sensors are not very sensitive to changes in structural parameters. Design and manufacturing error is restricted to a minimum. The sensor's prowess is investigated using the "finite element" approach (FEM). This paper demonstrated a theoretical study of a partially gold-coated photonic crystal fiber (PCF) based on surface plasmon resonance. In verifying sensing accuracy, the proposed sensor is not very sensitive to changes in structural parameters. Design and manufacturing error is restricted to a minimum. The prowess of the sensor is researched with the method “finite element” (FEM). The proposed model shows maximum wavelength sensitivity of 14000 nm/ RIU (Refractive Index Unit) with a sensor resolution of 7.14x10-6 RIU. Also, the maximum amplitude sensitivity is reported to be 4779.7 RIU-1. The calculation is performed in the refractive index range of 1.33-1.41. The introduced device may be a better alternative for biosensors because of its simple structures, linear trait, and high sensibility.
