摘要:
近年来,Airy光束作为一种无衍射光束,其特性引起了研究者的广泛关注,人们对它的理论研究、实验验证、实际应用多个方面都取得了长足的进步.而Airy光纤作为一种可生成Airy光束的波导器件,结合其光纤自身优点可适用于多种应用领域,因此开展新型Airy光纤的探索研究、拓展Airy光束的应用范围具有重要现实意义.本文从Airy光束的原理、光纤结构设计、光纤内部光束生成机理、生成光束波长响应特性以及Airy光纤研究现状和应用五个方面展开了较系统的讨论.
Abstract:
Recently,Airy beam as a kind of non-diffracting beam,has attracted a great deal of attention due to its unique properties to have propagationoinvariant intensity profile,remain transverse accelerating and exhibit "self-healing" features.Therefore,Airy beams have found many potential applications,such as optical micro-manipulation,imaging technology,surface plasmon polaritons and laser micromachining.Airy optical fiber as a kind of waveguide device can be applied for the Airy beam generation,carry out the exploration of new Airy fiber and expand the Airy beam application range,has important practical significance.In this paper,we give an systematical introduction from the view of the Airy beam working principle,Airy fiber structure design,Airy fiber beam generated internal mechanism,Airy beam wavelength response characteristics,and Airy fiber applications.
