A meta-heuristic method to design Erbium-Doped Fiber Amplifier (EDFA) Module for Dense Wavelength Division Multiplexing (DWDM) Network is proposed. By combining Simulated annealing (SA) and coupled mode theory, we obtain a promising method for the design of Long Period Gratings (LPGs) based gain equalizer for EDFA module. In C-band from 1528.8nm to 1562.3nm, we get the EDFA gain fluctuation within 1.1dB.
