INTERFEROMETRIC TECHNIQUE TO CHARACTERIZE OPTICAL FIBRES AND INTERROGATE GUIDED-WAVE-BASED MICRO- RESONATOR-SENSOR

摘要

In the frame of development of new reference techniques, LNE has developed a Phase sensitive-Optical Low Coherence Reflectometer dedicated to the characterization of optical fibres less than one meter long and to the interrogation of guided-wave-based biosensors. Thus this technique is within the fields of optical telecommunication and biological applications. In this context: standard fibres, Bragg gratings, specialty fibres such as photonic crystal fibres and sensors made of micro-resonators have been studied. This tool has proven to be very performing as it gives relevant parameters with low uncertainty on components not accessible with other techniques or needed several different techniques. The setup is presented as well as the results of particular interest obtained on optical waveguides in the telecommunication and biological domains.
