摘要: 轴对称矢量光束包含径向偏振和角向偏振,具有独特的强度和偏振分布,在表面等离子体激发、激光光镊和高分辨成像等领域有重要应用。光纤中的二阶本征模式TM01和TE01分别具有径向偏振和角向偏振的性质,可用于产生轴对称偏振光束。本文介绍基于少模光纤光栅的全光纤轴对称偏振光束的产生方法。

Abstract: Cylindrical vector beam including radially polarized and azimuthally polarized beam have drawn great attention because of their unique features in intensity and electrical distributions which are applied in variety of area such as plasmon excitation, optical tweezers and high-resolution metrology. Few-mode fibers are used to generate CVB due to their second order eigenmodes, TM01 and TE01 are, exactly, of radial and azimuthal polarization. In this paper, we introduce our works focusing on all-fiber laser generating CVB based on few-mode fiber Bragg grating(FMFBG)

Key words: waveguide and fiber optics; cylindrical vector beam; few-mode FBG;modes in fiber
