Abstract Multilayer models for single mode optical fiber based on Long Range Surface Plasmon Resonance (LRSPR) coated with silver (Ag) and gold (Au) with dielectric function of MgF2 are introduced. Properties for the models are theoretically and experimentally reported in this work. Firstly, the performances of different models are investigated using COMSOL simulation. Different combinations of magnesium fluoride (MgF2) and Ag/Au material embedded layers are applied to observed functionality of dielectric layers underneath the analyte. In theoretical analysis, MgF2-Ag and MgF2Ag-MgF2 layers conveys the best performance in sensing. The combination of plasmonic material Ag with MgF2 rather than Au shows higher sensitivity response. The experimental has been carried out with these configurations where exhibit the sensitivities of 1762.5 nm/RIU and 1250 nm/RIU at 1.371.38 and 1.33-1.34 RI range respectively for silver-based models. The outcomes indicate the proposed LRSPR based models with specific dielectric where here MgF2 found to be a strong match in sensing applications.

Dual Core

A surface plasmon resonance (SPR) sensor based on a dual-side polished microstructured optical fiber (MOF) with a dual core is proposed for a large analyte refractive index (RI; na) detection range. Gold is used as a plasmonic material coated on the polished surface, and analytes can be directly contacted with the gold film. The special structure not only facilitates the fabrication of the sensor, but also can work in the na range of 1.42–1.46 when the background material RI is 1.45, which is beyond the reach of other traditional MOF-SPR sensors. The sensing performance of the sensor was investigated by the wavelength and amplitude interrogation methods. The detailed numerical results showed that the proposed sensor can work effectively in the na range of 1.35–1.47 and exhibits higher sensitivity in the na range of 1.42–1.43.
