Recently, a single-mode core highly concentrated erbium-ytterbium codoped optical fiber (SM-EYDF) has been developed as a signal light amplifier that can more efficiently pump light in the 1550 nm band used in optical communications. Although we succeeded in generating light in the 1550 nm band by injecting sunlight into this structure, there was a problem that the emitted light was small. In this research, we used a solar lighting system different from those used in the past, and used solar excitation. We report the results of our efforts to increase the emitted light in the 1550 nm band.
