The superposition of spontaneous emission noise on a train of soliton pulses produces a random change of the center frequency of the soliton spectrum that causes a change of the group velocity of individual solitons, which in long-light-wave systems translates into a random jitter of the position of the pulses at the receiver. This phenomenon is known as the Gordon-Haus effect. If uncontrolled, the Gordon-Haus effect sets a definite limit on the permissible data rate or on the length of soliton-based light-wave systems. Recently Kodama and Hasegawa [Opt. Lett. 17, 31 (1992)] have shown that the Gordon-Haus effect can be suppressed by placing filters along the fiber that reduce the frequency jitter and the concomitant group-velocity changes. We demonstrate the reduction of the Gordon-Haus effect by computer simulations.
自发辐射噪声叠加在一列孤子脉冲上，会使孤子频谱的中心频率产生随机变化，从而导致单个孤子的群速度发生变化，在长光波系统中，这会转化为接收器处脉冲位置的随机抖动。这种现象被称为戈登 - 豪斯效应。如果不加以控制，戈登 - 豪斯效应会对基于孤子的光波系统的允许数据速率或长度设置明确的限制。最近，儿玉和长谷川[《光学快报》17, 31 (1992)]表明，通过沿光纤放置滤波器来降低频率抖动和随之而来的群速度变化，可以抑制戈登 - 豪斯效应。我们通过计算机模拟证明了戈登 - 豪斯效应的减小。
