在最近的出版物[Opt. Lett.43，4727（2018）OPLEDP 0146 -959210.1364/OL.43.004727]中表明，结构化1D源复相干态的相位会破坏远场谱密度的笛卡尔对称性，导致其单侧径向加速度，不对称分裂和其他效应。我们将这一结果从1D扩展到2D（标量）光束，并考虑新的2D源的例子与可分离的（在笛卡尔坐标）和不可分离的相位分布的复杂的相干态，说明在不对称操作的2D远场的可能性。
It was shown in a recent publication [Opt. Lett.43, 4727 (2018)OPLEDP0146-959210.1364/OL.43.004727] that structuring the phase of 1D-sourced complex coherence states results in breaking the Cartesian symmetry for the far-field spectral density, leading to its one-sided radial acceleration, asymmetric splitting, and other effects. We extend this result from 1D to 2D (scalar) optical beams and consider examples of novel 2D sources with separable (in Cartesian coordinates) and nonseparable phase distributions of the complex coherence states, illustrating the possibilities in asymmetric manipulation of the 2D far-fields.
