Investigate C+L Band EDFA/Raman Amplifiers by Using the Same Pump Lasers

  title={Investigate C+L Band EDFA/Raman Amplifiers by Using the Same Pump Lasers},
  author={Shien Kuei Liaw},
A hybrid C+L band erbium-doped fiber amplifier/Raman fiber amplifier (EDFA/RFA) is constructed by sharing common 1480 nm pump source(s). It is based on three-level amplification mechanism in the C band and Raman shift amplification mechanism the in L band, respectively. The gain spectra of C+L band are flattened by optimally dividing the pump power ratio of 1:29 for EDFA/RFA. Gain variation is 14±1 dB for the C band EDFA and 13±1.5 dB for the L band RFA without gain equalization. The low noise… CONTINUE READING
