| 795 nm and 1064 nm dual pump thulium-doped tellurite fibre for S-band amplification (2002) | |||||||||||
Abstract | |||||||||||
| Gain measurement in thulium-doped tellurite fibre is demonstrated with a maximum internal gain of 7 dB at 1480 nm. An improvement in gain by a factor of 2 is achieved using a 795 nm and 1064 nm dual pump scheme. Gain in tellurite fibres extends to longer wavelength than in fluorides, showing improved overlap with the C-band EDFA. | |||||||||||
