  • Tunable multicolored patterns from photonic cross communication between cholesteric liquid crystal droplets
    Noh, JungHyun ...
    Monodisperse droplets of planar-aligned cholesteric (N*) liquid crystal exhibit an intriguing capacity for photonic cross communication, giving rise to colourful patterns that depend sensitively on ... N* pitch, droplet positions and illuminated area. The phenomenon results from a combination of omnidirectional selective reflection of N* droplets---which thus act as spherically symmetric self-assembled photonic crystals---and total internal reflection at the continuous phase surface. We outline how the unique optical properties can be employed in numerous applications.
