摘要
对孤子对在EDFA中的放大进行了研究。数值研究表明,孤子对在EDFA中能得到放大,但放大过程中孤子间距减小,孤子间形成小脉冲。引入非线性增益后,孤子对得到较大程度的放大,孤子间距减小程度降低,仍有小脉冲;引入初始啁啾后,孤子对得到放大,程度不如单独引入非线性增益时,孤子间距不变,无小脉冲产生;共同引入非线性增益和初始啁啾后,孤子对得到较大程度的放大,且孤子间距不变,没有小脉冲产生。
The amplification of soliton pair in EDFA was researched.The numerical research showed that the soliton pair could be amplified in EDFA,but the distance between solitons reduced in the process of amplification,and a small pulse was generated.After introducing nonlinear gain,the soliton got a greater degree of amplification,the degree of the reducing distance between soliton pairs was less than before,and still had a small pulse.After introducing the initial chirp,the degree of amplification was less than that introducing nonlinear gain,the distance between soliton pairs was not changed,and the small pulse was not generated.After introducing nonlinear gain and initial chirp,the soliton got a greater degree of amplification,the distance between soliton pairs was not changed,and the small pulse was not generated.
