Non-circular core, all silica fibers for irradiation and sensing medical applications

摘要

Medical treatments benefit from increased sharpness of radiation emission or detection. Noncircular core silica/silica optical fibers have benefits of better control of irradiation of diseased tissue and more uniform irradiations. Description of tested fiber structures and others available are presented Data will be presented on mechanical reliability of such fibers, primarily, medium-to-long term static fatigue experiments as well as shorter term strength experiments. Spectral behavior will also be presented. The loss of radial symmetry provides for more uniform output across the core face. These fibers have mechanical properties remarkably as good as standard circular core fibers, with high dynamic strengths and very good Static Fatigue Parameters.
