✦ Synopsis

We report on a new type of hybrid broadband superfluorescent fiber source (SFS) that uses a thulium-doped fluoride fiber (TDF) and an erbium-doped fiber (EDF) pumped by semiconductor diode lasers. This source has a total emission power of about 28 mW. A power density of more than )20 dBm/nm was obtained for over 150 nm, from 1460 to 1610 nm. A power density stability better than 0.05 dB/nm was also observed. Moreover, the generation of broadband SFSs in the S band and C + L band will also be discussed.

## Abstract By using a broadband fiber mirror (BFM), a wavelength tunable erbium‐doped fiber laser (TEDFL) is demonstrated composed with tunable fiber Bragg grating (TFBG). The BFM acts as a broadband reflector both for the lasing signal and pump source. At pumping power of 100 mW, stable laser out

The C-band is demonstrated to be suitable for pumping L-band erbium-doped fiber laser (EDFL) with a broad pumping band. A high power C-band superfluorescent fiber source (SFS) peaked at 1545 nm with output power of 1.86 W is constructed and utilized as pump source for L-band EDFL. Based on this, an
