We demonstrate a soliton self-frequency shift of approximately 120 nm in a fiber with 1.56-microm pulses generated at a 10-GHz repetition rate by an actively mode-locked laser. A highly nonlinear photonic crystal fiber with a length of only 12.6 m and a nonlinear coefficient of 62 W(-1) km(-1) is used to achieve such broadband operation. The wavelengths of the resulting sub-300-fs solitons can be tuned effectively by adjusting the input power. The maximum output power of the solitons exceeds 200 mW.
我们展示了在一根光纤中孤子自频移约120纳米，该光纤中由主动锁模激光器以10吉赫兹的重复频率产生1.56微米的脉冲。使用一根长度仅为12.6米且非线性系数为62瓦⁻¹千米⁻¹的高非线性光子晶体光纤来实现这种宽带运行。通过调整输入功率，可以有效地调谐所产生的亚300飞秒孤子的波长。孤子的最大输出功率超过200毫瓦。
