Abstract

An optical fiber refractometer based on lossy mode resonance (LMR) supported by a TiO2 coating has been designed and fabricated for the first time. The Layer by Layer (LbL) method, used to deposit the film, makes possible to tune the sensitivity and the operation wavelength of the device. The LMR absorption peak, located in the infra-red region, is highly sensitive to changes in the refractive index (RI) of the surrounding medium, showing a sensitivity of 2228 nm/RIU.
