Abstract

We previously demonstrated that Mie scattering of stationary partially coherent light by dielectric spheres generates coherence vortices. In this Letter, we demonstrate that a lattice of coherence vortices can be generated by Mie scattering of partially coherent electromagnetic waves by a system of three coplanar dielectric spheres. Spontaneous coherence-vortex creation and destruction is observed in our computer modeling of this system.

摘要

我们之前已经证明，介电球体对定态部分相干光的 Mie 散射会产生相干涡旋。在这篇文章中，我们证明了通过三个共面介电球体的系统对部分相干电磁波的 Mie 散射可以产生相干涡旋晶格。我们对该系统的计算机建模中观察到了自发相干涡旋的产生和湮灭。
