Vector vortex waveplates offer distinct advantages compared to conventional light blocking components for coronagraphs due to their continuous structure, thinness, and transparency. They allow high contrast over a broad band in any spectral region for which the available anisotropic optical materials are transparent. We present opportunities of reducing in-band leakage of vector vortex waveplates to <0.001% level, and improving the tradeoff between the spectral bandwidth and efficiency. Comparative analysis of different architectures of vector vortex waveplates is performed.
