【摘要】 拉曼增益谱的一个重要特征是增益峰值波长仅与泵浦波长有关(固定偏移约100nm)。利用这一特性,设计了一种新的光纤拉曼放大器(FRA)多泵浦源的优化算法。利用这一算法及综合理论模型,研究了不同配置条件下FRA增益谱。结果表明,该算法是简单而有效的。更多还原

【Abstract】 An important feature of Raman gain spectrum is that the gain peak wavelength only depends on the pump wavelength (fixed shift about 100 nm).Based on this feature a new optimal algorithm for multipumped sources of distributed fiber Raman amplifier(FRA) was proposed .Using the algorithm and a comprehensive model the Raman gain spectra of multipumped FRAs under the various conditions were investigated.The results show that the optimal algorithm for the multipump sources of distributed FRAs is simple and effective.更多还原
