Abstract

Gain bandwidth expansion is one of the best ways to increase transmission capacity.1 Gain bandwidth can be expanded toward shorter or longer wavelengths. However, expansion toward the L-band presents difficulties due to micro and macro bending problems of fibers. In this work we investigate expanding gain toward the shorter (S–) wavelength range. Thulium-doped fiber amplifier (TDFA) pumped by 1047 nm Nd:YLF laser has a gain bandwidth around 1465 nm.2 However, to utilize the neighboring C-band, and also for practical use, the gain bandwidth has been shifted to the 1500 nm region by semiconductor LD pumping.3 The gain-shifted TDFA (GS-TDFA) seems mature, however, and there is no way to amplify the S+ band below 1470 nm, by pumping only with semiconductor LDs. For further expansion of gain bandwidth in this region, we need another means of amplification.
