Abstract
AbstractComplex propagation dynamics of higher‐order polarization singularities are investigated within tailored Poincaré beams. Spatial polarization modulation and additional phase vortices of higher strength are combined, evoking polarization singularity splitting, type conversion, creation and annihilation. These phenomena form singularity “explosions” along their longitudinal evolution. These dynamics of propagating customized light fields and embedded singularities are analyzed experimentally and numerically. Furthermore, similarities of polarization singularity explosion and phase vortex unfolding are discussed, exploring fundamental propagation and spatio‐temporal interaction properties of optical singularities.
