当掺铒光纤放大器中的碰撞集中时，不同波长的孤子表现出显著的光谱和时间变化。通过使用两个孤子脉冲串，其中∼的脉冲宽度为70ps，被1.8A和106公里的非色散位移光纤光谱分开，我们观察到每个孤子的光谱和时间漂移分别高达0.35A和55ps。这两个孤子波长的移动量相同，但方向相反，在碰撞后在形状和幅度方面保持不受干扰。这种转变可能会对利用光纤放大器的基于多波长孤子的通信系统施加限制。
Solitons of different wavelengths are found to exhibit substantial spectral and temporal changes when collisions are centered in erbium‐doped fiber amplifiers. By using two soliton pulse trains, with ∼70‐ps‐wide pulses, spectrally separated by 1.8 A, and 106 km of non‐dispersion‐shifted fiber, we observe a spectral and temporal shift of as much as 0.35 A and 55 ps, respectively, for each soliton. Both soliton wavelengths shift the same amount, but in opposite directions and remain undisturbed in terms of shape and amplitude after the collision. This shift may impose limitations on multiple wavelength soliton based communication systems utilizing fiber amplifiers.
