Abstract
We have developed a gain-shifted thulium-doped fiber amplifier (TDFA) with a high-optical efficiency (29%) and a high-output power (+21.5 dBm) operati ng in the 1480-1510-nm wavelength band by employing a novel laser-diode pum ping scheme of 1.4 and 1.56 mum The results we obtained confirm the feasibi lity of applying our gain-shifted TDFA to practical wavelength-division-mul tiplexing (WDM) networks.
