Paper Abstract
This work presents an application of polymer-clad silica (PCS) multimode optical fiber coated with high refractive index (nD>2.4) silicon nitride (SiNx) nano-overlay for refractive index (RI) sensing. The nano-overlay was deposited on 2.5 mm-long section of the fiber’s core using radio-frequency plasma-enhanced chemical vapor deposition (RF PECVD) method. We show that spectral response of the sensor to external RI strongly depends on the overlay deposition time. For just 6 min-long process the sensitivity calculated as a shift of the resonance observed in the transmission spectrum at about λ=600 nm with RI reaches 690 nm/RIU. The experimental results have been compared to numerical simulations.
