Polarization domain splitting and incoherently coupled dark-bright vector soliton formation in single mode fiber lasers

We have experimentally investigated the polarization dynamics of a weakly birefringent cavity single mode fiber laser under different laser operation conditions. We show features of polarization domain formation, domain splitting, and domain shaping into dark-bright vector solitons under incoherent cross-polarization coupling.Agency for Science, Technology and Research (A*STAR)Ministry of Education (MOE)National Natural Science Foundation of China (61875078); Priority Academic Program Development of Jiangsu Higher Education Institutions; Agency for Science, Technology and Research (A1883c0003); Ministry of Education–Singapore (RG18/106)
