説明:

A single-mode erbium-doped optical fiber (SM-EDF) and a single-mode erbium–ytterbium co-doped optical fiber (SM-EYDF) were pumped using solar light. As a result, emitted light in the 1550 nm band was observed. Furthermore, we compared the emission properties of SM-EDF and SM-EYDF. The emission peak of SM-EYDF was more than twice as high as that of SM-EDF. The optimal fiber lengths for peak emission of SM-EYDF were found to be approximately 18.8 cm in the present experiment environment. This paper is the first to apply SM-EYDF to solar pumping and conduct detailed investigations, including fiber length characteristics. The possibility exists that increasing the power output and introducing oscillation systems fibers can make them applicable to long-distance optical communication light sources and amplifiers driven solely by solar light.
