Pump-controlled gain-locked Raman fibre amplifier
Karásek, Miroslav
Preliminary results of numerical simulation of pump-controlled, gain-locked Raman fibre amplifier have been presented. Numerical model of the gain-locked amplifier is based on interative solution of propagation equations for pumps, signals and spectral components of amplified spontaneous emission. Proportional-derivative feedback loop which controls the pump power has been implemented. Suppression of surviving channel power fluctuations due to channel addition/removal has been investigated.

Power transients in Raman fiber amplifiers
Karásek, Miroslav
Output power transient in Raman fibre amplifiers /RFA/ have been investigated both theoretically and experimentally. Large signal numerical model of RFA has been used for the analysis. It has been that substantial power transients can occur when WDM channels are dropped/added.
