Efficient amplification in the first telecommunications window

Record type: Conference or Workshop Item (Paper)

Thulium-doped fluorozirconate fibre can be used as an efficient amplifier over the wavelength range 800-815 nm in the first telecommunications window. A small-signal gain of 23 dB has been achieved at 805 nm with 50 mW of launched pump power at 780 nm. The fibre used for this demonstration had 21 core diameter of 3.5 µm, numerical aperture 0.16 and thulium ion concentration ~800 ppm by weight. The background loss of the fibre was measured to be less than 0.1 dBm. These results suggest that a high gain 800 nm amplifier employing an AlGaAs diode-pumped thulium-doped fluorozirconate fibre can now he made.
