Abstract

An effort to reduce UV-induced defect centers and improve the UV solarization resistance in a high –OH synthetic fused silica step index multimode optical fiber, designated as FDP, was successfully completed at Polymicro Technologies. The development achieved significant reduction in the 214 and 265nm absorption bands typically associated with solarization effects in fused silica. The improvements were applied to fiber core diameters from 68 to 600μm. Characterization of the solarization resistance was performed with added attenuation from UV exposure demonstrated to be less than 1dB per two meters tested for all fibers in the core size range. Results of spectral performance and UV degradation are presented along with a description of the test protocols. Potential applications in the medical and spectroscopy fields also will be discussed.
