Self-Healing Property of Two-Dimensional Airy Beams
摘要
通过数值仿真研究了不同区域被阻挡时无衍射二维艾里光束的自愈特性。仿真结果表明,部分区域被阻挡时,光束在传输一定距离后能进行自我重构。同时研究了高斯噪声环境下无衍射二维艾里光束的自愈特性。结果显示,在一定的信噪比下艾里光束经过一定距离的传输后也能够自愈。这种自愈具有一定的稳健性。艾里光束的自愈特性能够应用于光镊系统、微粒自陷和操控、光无线通信等众多领域。
Abstract
The self-healing property of non-diffracting two-dimensional Airy beams with different parts blocked is investigated via numerical simulation. The simulation shows that the Airy beams that are partially blocked can be self-reconstructed after propagating for a certain distance. The self-healing property under the Gaussian noise perturbation is also investigated. The result shows that self-healing of the Airy beams can be realized after the beam propagates for a certain distance when the signal-to-noise ratio is appropriate. The self-healing property of Airy beams is robust, and the property can be applied in many fields such as optical tweezer system, atom trapping and manipulating, and wireless optical communications.
