Abstract

The project cover the realization of research internship abroad at Institute for Photonics and Advanced Sensing (IPAS), in the University of Adelaide at Adelaide, Australia, through the program BEPE - FAPESP for a period of 12 months. The work aims to fill a gap and provide new contributions for the development and experimental implementation of microstructured optical fibers (MOF) as real-time sensor of temperature and strain, based on nonlinear optical effects of Raman and Brillouin scatterings. This research project perfectly complements the post-doctoral work in developing, entitled Special optical fibers based on tellurium oxide for nonlinear optical applications (Process number 2010/20776-5 FAPESP). The Australian group have produced several relevant works into this research area and dominates the extrusion technique which allows reproducibility and build complex structured optical fibers. MOF will be produced from optimized and characterized preforms, which will be sensitivity tested by varying the distributed temperature and strain along the optical fiber, through monitoring the Raman and Brillouin shifts (nonlinear optical effects) of the transmitted signal on output fiber. Based on the results obtained, the aim is build the sensing device using microstructured optical fibers. (AU)
