We describe the experimental discovery of a continuous shift in the optical frequency of a soliton pulse as it travels down the fiber. The effect is caused by a Raman self-pumping of the soliton, by which energy is transferred from the higher to the lower-frequency parts of its spectrum. For 120-fsec pulses, we have observed net frequency shifts as great as 10% of the optical frequency.
我们描述了孤子脉冲在光纤中传输时其光频率发生连续变化的实验发现。这种效应是由孤子的拉曼自泵浦引起的，通过这种自泵浦，能量从孤子频谱的高频部分转移到低频部分。对于120飞秒的脉冲，我们观察到净频移高达光频率的10%。
