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)
