A flat high efficiency super-broadband source was presented. We achieved a C+L-band superfluorescent source, in the region from 1524. 0 to 1600.4nm, the power of the ASE are over -12. 0dBm and the ASE profile excursion is only ±1. 4dB in the region from 1539. 2 to 1600.4nm. The power of the ASE is 22. 1mW and the power conversion efficiency is 18. 8%. 9. The amplification characteristics of thulium-doped fiber amplifier had been studied using the basic theory for fiber amplifier. The connection between the Tm-doped fluoride fiber and silicon fiber was accomplished, and we studied the TDFA and the reason that the expecting results hadn't achieved had been analyzed. The assumption of the Er-Tm-co-doped silicon fiber had been presented, and we studied the Er-Tm-co-doped silicon in cooperation with the correlative corporation, some results had been got and the further studies are carried on.
