We report the observation of a nonlinear propagation scenario in which a dispersive wave is transformed into a fundamental soliton in an axially varying optical fiber. The dispersive wave is initially emitted in the normal dispersion region and the fiber properties change longitudinally so that the dispersion becomes anomalous at the dispersive wave wavelength, which allows it to be transformed into a soliton. The solitonic nature of the field is demonstrated by solving the direct Zakharov-Shabat scattering problem. Experimental characterization performed in spectral and temporal domains show evidence of the solitonization process in an axially varying photonic crystal fiber.
我们报告了一种非线性传播情况的观测结果，即在轴向变化的光纤中，色散波被转化为基孤子。色散波最初在正常色散区域发射，光纤特性沿纵向变化，使得在色散波波长处色散变为反常，从而使其能够转化为孤子。通过求解直接的扎哈罗夫 - 沙巴特散射问题证明了场的孤子性质。在光谱和时域进行的实验表征显示了在轴向变化的光子晶体光纤中孤子化过程的证据。
