Depolarization issues with FBG-stabilized pump diodes regarding their use in copumped Raman amplifiers
24 September 2006
RIN transfer is characterized in a Raman amplifier copumped with a single depolarized FBG-stabilized diode. We reveal and analyze that, due to polarization selectivity, RIN transfer is 9dB higher than with two polarization-multiplexed FBG diodes.
