In this research work, low refractive index (RI) detection done on multi-core photonic crystal fiber (PCF) based highly sensitive surface plasmon resonance (SPR) sensor is propounded. Sensing the changes in neighboring medium’s refractive index is done by placing the plasmonic material i.e. Silver (Ag) over the crystal structure of fiber. On top of the Silver, a threadlike film of titanium dioxide (TiO2) is deposited to prevent oxidation of plasmonic material silver. Peak wavelength sensitivity thus achieved by this sensor is 127,600 nm/RIU and similarly, peak amplitude sensitivity achieved is 2561 RIU-1, respectively. Subsequently making this sensor suitable candidate for various applications such as biosensing, sensing organic compounds and chemicals, inspecting pharmaceuticals and other detections.

Square Array

Based on surface plasmon resonance (SPR), a novel refractive index (RI) sensor comprising a square photonic crystal fiber (PCF) is proposed to realize the detection of the annular analyte. Instead of hexagon structure, four large air-holes in a square array are introduced to enhance the sensitivity by allowing two polarization directions of the core mode to be more sensitive. The gold is used as the only plasmonic material. The design purpose is to reduce the difficulty in gold deposition and enhance the RI sensitivity. The guiding properties and the effects of the parameters on the performance of the sensor are numerically investigated by the Finite Element Method (FEM). By optimizing the structure, the sensor can exhibit remarkable sensitivity up to 7250 nm/RIU and resolution of [Formula: see text] RIU with only one plasmonic material, which is very competitive compared with the other reported externally coated and single-layer coated PCF-based SPR (PCF–SPR) sensors, to our best knowledge.
