Abstract

Optical fiber sensors based on the lossy mode resonance (LMR) effect obtained by means of the utilization nanoparticle-based thin-films are presented for the first time in this work. Tungsten oxide III nanoparticles (WO3NP) and diamond nanoparticles (DNP) have been deposited separately onto cladding removed multimode fiber to obtain LMRs. The fabrication of the thin-films was performed using the layer by layer (LbL) technique. Poly(allylamine hydrochloride) PAH was used in both cases to embed the nanoparticles. The LMRs obtained were characterized during the thin-film fabrication process allowing to precisely tuning the resonance in the desired part of the spectrum. Thin-film properties were studied using a scanning electron microscope (SEM) and optical microscope to verify their homogeneity and roughness. The response of the devices to changes in the surrounding medium refractive index (SMRI) was studied showing sensitivities of 5940 and 1368 nm/RI for WO3NP and DNP respectively, which opens the door to the utilization of these devices for novel sensing applications.
