“…To overcome this issue and effectively reduce time consumption, the use of a simplified analytical 5,12 or semianalytical 9 solution has been proposed for the calculation of the Raman gain profile. Moreover, previous reports of optimizations of multipump Raman amplifiers based on analytical calculation of the Raman gain profile 5,9,12 still present issues concerning the time consumption due to the use of slow optimization heuristics needing a huge number of iterations to achieve the desired result.
