Here, we report a superstructure of self-assembled chiral nematic microspheres of well-defined size that can distribute incoming light in any direction, while displaying high selectivity for the color and chi-rality of the incoming light. The cross-communication between the droplets can be tuned, both gradually in wavelength and reversibly in polarization.1 Monodisperse droplets are produced using a microfluidic device, and this monodispersity promotes the self-assembly of the droplets into hexagonal superstruc-tures, where they communicate optically with high selectivity for the color and chirality of light.
