WebJul 1, 2024 · We propose a novel method for the generation of a cylindrical vector beams (CVBs) laser in an all-polarization-maintaining fiber (PMF) configuration based on the principle of mode superposition. By using this method, a stable and high purity radially polarized (TM 01) mode is obtained by stretching fiber to adjust phase shift. WebAug 1, 2024 · We propose a linear mapping relationship between the polarization of the fundamental mode and the cylindrical vector (CV) modes on the first-order Poincare sphere (FOPS) in fiber. The new method is based on the four-dimensional complex Jones matrices in terms of the linearly polarized mode bases.
