    Optical Fiber by Solar Pumping

## Description

- description: 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.
