We propose and optimize a hybrid erbium-doped fiber amplifier/fiber Raman amplifier (EDFA/FRA). A large number of parameters of a wide-band hybrid amplifier consisting of an erbium-doped fiber amplifier (EDFA) and a fiber Raman amplifier (FRA) have been optimized using an effective and fast global optimization method called particle swarm optimization. Two types of hybrid EDFA/FRA with six- and 10-pumped FRAs have been optimized. A large number of variables affect the hybrid EDFA/FRA performance, thus we need a global optimization method to be able to deal with these variables. Particle swarm optimization helps us to find optimum parameters of a hybrid EDFA/FRA and reduce the gain spectrum variations to 2.91 and 2.03 dB for the six and 10 pumped FRAs, respectively. The optimum design supports the amplification of 60 signal channels in the wavelength range of 1529.2-1627.1 nm for a wavelength-division multiplexing system.
我们提出并优化了一种混合掺铒光纤放大器/光纤拉曼放大器（EDFA/FRA）。使用一种名为粒子群优化的有效且快速的全局优化方法，对由掺铒光纤放大器（EDFA）和光纤拉曼放大器（FRA）组成的宽带混合放大器的大量参数进行了优化。已对具有六个泵浦和十个泵浦的光纤拉曼放大器的两种类型的混合EDFA/FRA进行了优化。大量变量会影响混合EDFA/FRA的性能，因此我们需要一种全局优化方法来处理这些变量。粒子群优化帮助我们找到混合EDFA/FRA的最佳参数，并将六个泵浦和十个泵浦的光纤拉曼放大器的增益谱变化分别降低到2.91 dB和2.03 dB。该优化设计支持波分复用系统在1529.2 - 1627.1 nm波长范围内对60个信号通道进行放大。
