Abstract
Cholesteric liquid crystal droplets are self-assembled spherical photonic crystals. Multiple droplets in the same plane communicate optically, giving rise to unique patterns of circularly polarised and strongly coloured spots. We explain the phenomenon and outline routes to application.Keywords
