Optical quasiparticles such as optical skyrmions have been studied theoretically and experimentally demonstrated as an emerging topics. The present work demonstrates a novel and robust technique for converting phase singularity into polarization singularity through single-pass phase modulation of the input beam. The proposed approach simplifies the experimental setup and enables flexibility in the generation of different forms of topologically protected polarization textures, including topological conversion from C-point to V-point polarization singularity or otherwise. Our proposed method can be useful for diverse applications of optical quasiparticles, such as for classical and quantum information processing, communications, and chiral material sceinces.
