We report the experimental observation of dispersive wave emission from gray solitons propagating in the normal dispersion region of an optical fiber. Besides observing for the first time, to the best of our knowledge, the emission of a dispersive wave from an isolated dark soliton, we show that the dispersive wave frequency and amplitude strongly depend on soliton grayness. This process can be explained by the higher-order dispersion contribution into the phase-matching condition and the grayness of the soliton. Numerical simulations and theoretical predictions are in good agreement with the experiments.
我们报告了在光纤正常色散区域中传播的灰色孤子产生色散波发射的实验观测结果。据我们所知，除了首次观测到孤立暗孤子发射色散波外，我们还表明色散波的频率和幅度强烈依赖于孤子的灰度。这个过程可以通过高阶色散对相位匹配条件的贡献以及孤子的灰度来解释。数值模拟和理论预测与实验结果吻合良好。
