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:
