Research on the fiber's UV transmission performance influenced by the doping process

摘要

With the increasing application in the ultraviolet (UV) area, the fiber's UV transmission performance should be studied. In UV fibers, however, the presence of Germanium can result in ultraviolet radiation-induced color centers, which are point defects in the core's silica that generate absorption bands in the UV and visible spectrum that deteriorate the optical fiber transmission in that spectral region [1]. The fiber's UV transmission performance would be influenced by the fiber core's doping content. Based on the advanced plasma chemical vapour deposition process, three types of different doping content fibers were fabricated. With test these fibers' transmission efficiency and stability, study the optimized doping process of the UV fiber.
