Abstract

In this work, is presented the fabrication and characterization of optical fiber refractometer based on the lossy mode resonances (LMR). Indium-tin-oxide and tin dioxide thin films deposited on optical fibers are used as the LMR supporting coatings. These resonances shift to the red as a function of the external refractive index. The refractometer has been used to characterize the degradation of a synthetic industrial gear lubricant oil at working temperature.
