New Possibilities for Using Specialty Optical Fibers

The results of the development and creation of various specialty optical fibers (SOF) for application in science and engineering are presented. Methods of producing SOF with Bragg structures written directly into the light-guiding core during fiber drawing are described. Based on these SOF, reflectometric sensors and single-frequency laser complexes have been developed. By means of precision thinning of the reflecting coating and deposition of nanoparticles, fiber optic liquid refractometers have been produced. The ways of using multicore SOF and the possibilities of creating final probes based on them are demonstrated.
