High-power erbium-doped fibre amplifier pumped by a phosphosilicate fibre Raman converter

摘要

A high power erbium-doped fibre amplifier pumped by single-mode radiation at 1478 nm is fabricated and tested. A Raman converter based on a fibre with a phosphosilicate core was used as the pumping source. The maximum output power achieved in spectral ranges C (1.53-1.56 μm) and L (1.56-1.60 μm) is 28 dBm.
