| 摘 要： | 为了研究双级双抽运结构C+L波段放大自发辐射宽带光源的两级光纤长短搭配不同对输出光谱特性的影响,采用软件模拟仿真和实验验证相结合的方法,进行了理论分析和实验对比。结果表明,当第1级光纤较短、第2级光纤较长时,可实现功率为18.04mW(12.56dBm)、抽运光利用效率为13.9%、平坦度小于±3.97dB(1525nm～1600nm)的C+L波段放大自发辐射输出;当第1级光纤较长、第2级光纤较短时,可实现功率为20.07mW(13.02dBm)、抽运光利用效率为16.7%、平坦度小于±1.89dB(1525nm～1600nm)的C+L波段放大自发辐射输出。采用第1级光纤较长、第2级光纤较短的双级双抽运是一种更为理想的C+L波段放大自发辐射光源结构。

| Abstract: | In order to study effect of the matched fiber lengths of the dual-stage dual-pump C+L band Er-doped fiber sources on the output spectra, numerical simulation and experimental verification were carried out. The results showed that with shorter first stage fiber and longer second fiber, the output power was 18.04mW(12.56dBm) with the pump conversion efficiency of 13.9% and the flatness(from 1525nm to 1600nm) was less than ±3.97dB; on the contrary, the output power was 20.07mW(13.02dBm) with pump conversion efficiency of 16.7%, the flatness(from 1525nm to 1600nm) was less than ±1.89dB. The comparative analysis results for both the cases show that the latter is superior to the former. |
