- Optical skyrmions, which are topological protection quasi-particles with nontrivial textures, hold a pivotal focus in current structured light research for their potential in diverse applications. In this work, the angular spectrum theory is first introduced into the generation of optical skyrmions and modulation of the intensity and trajectory of skyrmions at will. We propose a novel theoretical approach for the generation of skyrmions, including Neel-type, Bloch-type, anti-type and 2nd order. The simultaneous and independent modulation of intensity distribution and trajectory of isolated skyrmions is first achieved with the combination of phase-shifting theory with angular spectrum theory. By controlling the displacement phase factor (DPF), the customized shape of skyrmions array with controllable intensity distribution and trajectory is also generated. Our findings in this work allow a greater exploration of skyrmions, which promote applications in particle manipulation and high-density storage.
