N2 - We propose and demonstrate production of a supercontinuum vector beam by independent manipulations of an angular polarization and a geometric phase. The proposed concept consists of left- and right-hand vortex phase cancelation. Two-dimensional distributions of the angular polarization and the geometric phase in the generated vector beam are evaluated for a rigorous polarization analysis. Their azimuthal angles are linearly changed with matching ratios of more than 90%, as compared to the theoretical calculations. The geometric phase obtained from ellipsometric parameters is also shaped to be a uniform phase at an average of 0.10 rad and to angularly decrease the vortex phase up to -6.73 rad, respectively. Our strategy is sufficient for finding numerous applications, such as super-resolution microscopy, plasmonics, and spectroscopy.
