Noise Performance Improvement of Broadband Discrete Raman Amplifiers Using Dual Stage Distributed Pumping Architecture

Online versus Offline Optimization Methods for Raman Amplifier Optimization

“…The ability to provide broadband gain at any frequency has recently motivated researchers to consider Raman amplifiers (RA) for the amplification of multi-band signals [1]- [5]. Some of the aforementioned works have explored an exclusive RA feature: the shaping of gain spectrum by adjusting the powers of the pump lasers.…”
