A novel polymerizable cholesteric liquid crystal (CLC) is presented as a candidate for holographic data storage. In contrast to classical photopolymers, which require a spatially varying intensity, the CLC is able to store polarization holograms (see Figure) with a constant intensity but spatially varying polarization (RCP and LCP denote right‐ and left‐circularly polarized light, respectively) (see also cover).
