An emerging vision for future advances in the modern photonics is to explore the fundamental concepts of light coherently shaped in phase, amplitude, and polarization in different scenarios. In this paper, the conversion between linear and circular polarizations in free space by the beam itself is demonstrated theoretically and experimentally. Any two orthogonal polarizations can occur and auto‐focus at different propagation distances during the structured caustic vector optical field with radially‐variant states of polarization propagating in free space. The desired polarization states and the two foci can be flexibly managed by the initial caustic phase and polarization distributions.
