Recent progress in thulium-doped fiber amplifiers

SPIE Proceedings, 2003
I review the fast growing progress in thulium doped fiber amplifiers (TDFA) for S-band optical communication systems. The main results reported on pump schemes and amplifiers efficiencies are given. In particular, the characterization of TDFAs regarding distributed gain optimization using the coherent optical frequency domain reflectometry is described,

Photobleaching of thulium-doped ZBLAN fibers with visible light

Optics Letters, 1997
Photobleaching of darkened thulium-doped ZBLAN fibers is observed after short exposure to visible light. The bleaching process is characterized by a stretched-exponential function of time with an exponent beta independent of both the bleaching intensity and the thulium concentration.

Progress in thulium doped fiber lasers and aplifiers

SPIE Proceedings, 2012
We present results on the development of signal sources for the 2000 nm band. The ASE source is presented with a FWHM bandwidth of 70 nm and -20dB bandwidth of 229 nm with an integrated power of 7.5 mW. Narrow band lasers are presented made of a short piece of core-pumped thulium doped fiber and fiber Bragg gratings.

High-Power Thulium-Doped All-Fiber Superfluorescent Sources

IEEE Journal of Selected Topics in Quantum Electronics, 2014
Power scaling of broadband and narrowband thulium-doped all-fiber superfluorescent sources based on master-oscillator power-amplifier configuration is reported. For scaling the output-power of broadband superfluorescent fiber source, a stable low-power broadband superfluorescent fiber seed source and a two-stage cladding-pumped thulium-doped fiber ...

Recent advances in thulium-doped fiber amplifiers

Optical Fiber Communication Conference and Exhibit, 2002
Summary form only given. Presents a comparison between different pumping schemes implemented within fluoride doped fibers. The first part deals with the performances of different up-conversion pumps. In the second part, the advantages and drawbacks of several ground state pump wavelengths are discussed.
