Design and Performance Analysis of a Novel Hoop-Cut SPR-PCF Sensor for High Sensitivity and Broad Range Sensing Applications
IEEE Sensors Journal(2023)
Abstract
This paper presents a systematic numerical investigation of a surface plasmon resonance (SPR) sensor based on photonic crystal fiber (PCF). The proposed design is modeled and simulated using the full vectorial finite-element (FV-FEM) technique and sensing characteristics such as confinement loss behaviors, phase matching and sensitivity are investigated and presented. The plasmonic layer is made up of TiO
2
and gold for improved sensitivity. The reported sensor exhibits an amplitude sensitivity of -374.062 RIU
-1
and a wavelength sensitivity of 2000 nm/RIU for the refractive index (R.I.) sensing range of (1.39-1.44), according to the loss spectrum shift. The reported hoop-cut photonic crystal fiber surface plasmon resonance sensor is suitable for biosensing and chemical sensing applications because of its broad range (1.39-1.44) of analyte detection.
