A Photonic Crystal Fiber Based Asymmetric Slotted Structured Highly Sensitive Refractive Index Plasmonic Biosensor

Surface plasmon resonance (SPR) sensors have grown in popularity owing to their sensitivity, precision, and capacity for a variety of applications, including detection, monitoring, sensing, among others. Sensitivity resolution are two areas where this technology has room development. A plasmonic biosensor based on an asymmetric slotted PCF structure with extremely high sensitivity been described theoretically investigated. This performance sensor is constructed completely characterized using finite element method COMSOL Multiphysics software environment. analyzed as parameters the proposed sensor. Numerical simulation exhibits maximum wavelength-sensitivity 1100 nm/RIU 9.09 × 10-6 RIU broad measurement range refractive index from 1.30 1.44. polarization controller can be used fine-tune sensitive wide-ranging fulfil practical needs. performed consideration variation (RI) analyte channels. In comparison earlier PCF-based sensors, fiber design basic, symmetrical, simple produce, cost-effective. Because air holes higher sensitivities detector, it possible identify biomolecules, biochemicals other analytes.
