Using an ultrafast photonic first‐order differentiator applied on a partially coherent field, the generation of two correlated temporal waveforms is reported and their correlation properties upon linear and nonlinear propagation along the two orthogonal polarization axes of a dispersive optical fiber are studied. Temporal correlations are maintained in linear propagation whereas Kerr nonlinearity generates anticorrelated temporal intensity patterns for both partially and uncorrelated fields. Experiments are in close agreement with the theoretical analysis.

具有相干性的部分相干场的线性和非线性光纤传播

使用应用于部分相干场的超快光子一阶微分器，报告了两个相关时间波形的生成，并研究了它们在沿着色散光纤的两个正交偏振轴的线性和非线性传播下的相关特性。在线性传播中保持时间相关性，而Kerr非线性会为部分和不相关的场生成反相关的时间强度模式。实验与理论分析非常吻合。
