“…When the values presented in Table 3 are investigated in terms of gain ripple, it is seen that different parameters are used in each study 10 , 12 14 , 18 , 19 , 33 Some have different fiber lengths, and some have different pump and signal numbers. For this reason, it does not seem possible to make an objective comparison in terms of gain ripple.…”

“…If a solution X 1 presents better fitness values for all the objective functions than another solution X 2 , then X 1 dominates X 2 ; If X 1 is better than X 2 in one objective function and is not worse in the others, then X 1 weakly dominates X 2 [35].…”

“…In this paper, we chose a configuration with four pumps since this is a usual choice for multipump Raman amplifier systems 4,7,8,12 that allow high levels of gains (∼20 dB) to be obtained under very low levels of ripple (∼1 dB). The first and the second constraints represent the minimum and maximum limits of pump wavelengths and pump power, respectively.…”

“…1 However, in wavelength division multiplexing (WDM) telecommunication systems, it is important not only to have high gains, but also the gain should be made as flat as possible over the entire amplification window, so that different channels do not receive an uneven amount of power. To solve this problem, a number of approaches have already been proposed based on simulated annealing, 4 exhaustive search, 5 neural networks, 6 ant colony optimization, 7 swarm optimization, 8 but mainly genetic algorithms (GAs) or hybrid GAs (Refs. 2 This capability of shaping the gain profile over a very broad amplification band (>100 nm) by properly setting the arrangement of pump lasers is what makes Raman amplifiers unique tools in the design of telecommunication systems.…”
