Generation of cylindrical vector beams based on fiber Bragg gratings inscribed in ring core fibers
We propose a method for generating an all-fiber cylindrical vector beam (CVB) using a fiber Bragg grating (FBG) inscribed in a ring core fiber (RCF).The FBGs are inscribed using the femtosecond laser phase mask scanning technique, chosen for its large ring core diameter and low photosensitivity of the RCF.Additionally, a lateral offset splicing spot is introduced to couple the fundamental mode to the second-order modes.Switchable LP 01 and LP 11 mode lasers can be achieved.Meanwhile, azimuthally and radially polarized CVBs are successfully realized by adjusting the polarization controllers.
