Abstract

Complex optical vortex bundles produced by dislocations arranged in accordance with the group of symmetry $D_{1}, D_{2}, C_{4}$ are studied theoretically and experimentally. The spatial evolution of optical vortices is investigated for three types of spatial configurations based on the signs of dislocation topological charges. Theoretical predictions derived from the Fresnel diffraction integral and the hydrodynamic approach have been found to be consistent with each other and are in a good agreement with the experimental results. For all cases, the symmetry properties of the dislocation arrangement are shown to be imposed to optical vortex bundles produced. The observed dynamics provides new insights into the behavior of singularities in complex optical fields.

四束光学奇点空间演化

位错产生的复杂光学涡旋束按照对称群d1， d2, c4 $D_1, D_2，对C_4$进行了理论和实验研究。基于位错拓扑电荷的符号，研究了三种空间构型下光学涡旋的空间演化。由菲涅耳衍射积分和流体力学方法得到的理论预测结果是一致的，与实验结果吻合得很好。在所有情况下，位错排列的对称性都被施加到产生的光学涡旋束上。观察到的动力学为复杂光场中奇点的行为提供了新的见解。

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
