摘要: 光纤具有端面尺寸小且柔韧性好的优势,纤端器件(lab on tip)无需严格的空间准直和耦合光路,具有集成度高、操作灵活、系统稳定等特点.该文详细介绍了基于表面等离激元的全光纤纤端单Airy和双Airy光束设计的基本理论、产生条件及方法.利用聚焦离子束刻蚀技术在纤端金属表面制作缝和槽等微结构,实现了多种Airy光束.紧凑型全光纤纤端集成特种光束发生器件在光捕获、微粒子操纵、光束整形中将具有重要的应用.

关键词: 光束整形, 光纤, 表面等离激元, Airy光束

Abstract: Due to small cross section and flexibility of optical fber, lab on tip requires no strict spatial collimation and coupling, therefore has many advantages including high integration, flexible operation, and performance stability. Here we review basic principles, generation and optimization of plasmonic all-fber single and double Airy beams. Various Airy beams have been achieved from metallic slits and grooves on the fber end based on FIB milling. The compact all-fber integrated special beam shaping devices are of importance to realize all-fber optical trapping, microparticle manipulation, and beam shaping.

Key words: optical fber, Airy beam, beam shaping, surface plasmon polaritons
