| 英文摘要 | A bidirectionally pumped optical amplifier (200) comprises an active fibre (201), a first WDM coupler (204) and a second WDM coupler (205), a first pump: branch (220) coupled to said first WDM coupler (204) comprising a first laser (202) and a first grating (210), for introducing pump radiation into said active fibre (201) in a first direction, a second pump branch (230) coupled to said second WDM coupler (205) comprising a second laser (203) and a second grating (212), for introducing pump radiation into said active fibre (201) in a second direction, opposite to said first direction. The second laser has an output power PF. A first pump residual, having a power Pinj, is coupled into said second pump branch (230) from the active fibre (201) and injected into said second laser (203). The first pump branch (220) further comprises an optical isolator (211) for the pump radiation. The output power of the injected laser and the injected pump power residual are such that PF/Pinj>2. |
