      Thulium-Doped Fiber Amplifier (TDFA) are considered for long-haul transmission systems as they allow amplification in the S-band ( μm) thanks to the Tm 3+ emission at μm from the 3 H F 4 transition. Presently TDFA are fluoride based because of Cited by: 5. We investigate the operation of holmium-doped fibre amplifiers (HDFAs) in the µm spectral region. For the first time we demonstrate a diode-pumped HDFA. This amplifier provides a peak gain of 25 dB at nm with a 15 dB gain window spanning the wavelength range – nm with an external noise figure (NF) of dB. We also compare the operation of HDFAs when pumped at nm Cited by:

    In this work we report on the thulium-doped silica-based optical fibers with increased fluorescence lifetime of the 3F4 level thanks to the modification of the local environment of thulium ions by high content of alumina.
