本文研究了波长移动孤子在有源光子晶体光纤中的放大。当红移孤子在有源光子晶体光纤中在一定的光谱范围内获得光增益时，除了光放大外，孤子的红移速度也会显著增加，相应的孤子脉冲宽度也会显著减小。红移速度的急剧增加是由于放大和大的脉冲压缩。由于基孤子在放大过程中的自增强特性，产生了大的脉冲压缩。此外，增益引起的光孤子减速导致孤子与其相应的色散波之间的碰撞和光束反射的时间模拟的产生。我们的实验结果与模拟结果部分吻合。
We demonstrate the amplification of a wavelength-shifting soliton in an active photonic crystal fiber (PCF). When a redshifting soliton experiences optical gain in a certain spectral range in the active PCF, in addition to its amplification, the redshifting speed of the soliton is increased dramatically and the corresponding pulse width of the soliton can also be reduced down dramatically. The dramatical increase in the redshifting speed is due to the amplification and large pulse compression. Large pulse compression arises because of the self-reinforcing feature of the fundamental soliton during amplification. Furthermore, gain-induced deceleration of the optical soliton causes the collision between the soliton and its corresponding dispersive wave and the generation of the temporal analog of reflection of optical beams. Our experimental results coincided with the simulated results partly.
