摘要：

An efficient numerical model is proposed to generate cylindrical vector (CV) beams by use of a few-mode fiber Bragg grating (FM-FBG) written directly in an ytterbium-doped fiber (YDF). Based on multilayer method, we analysis the transverse modes competition between LP01 and LP11 modes under various conditions. We propose that a pure CV beam can be generated by completely depressing LP01 mode through a doughnut doping few-mode fiber or using a wavelength filter.
