Abstract
The advance in the nanotechnology and fabrication of micro- and nanostructures has significant impact on development of new optical sensors. Presented study focuses on the applications of the titanium dioxide (TiO2) thin films in fiber optic sensors. The concept of a sensing fiber optic interferometer integrating TiO2 thin film is presented. The cavity of this interferometer is delimited by a 80 nm film fabricated on the end-face of the standard telecommunication single mode optical fiber (SMF-28) by use of the Atomic Layer Deposition (ALD) and a protected silver mirror. The simulation of spectral reflectance of the thin film is performed and its performance in a multi-cavity structure of the fiber optic Fabry-Pérot interferometer is analyzed. The results show that proposed interferometer could be successfully implemented in optical fiber sensors of selected physical and biochemical quantities.
