Light-driven spectrum tunable Airy beams. a The theoretical α distribution of a CLC Airy beam generator and corresponding simulated Airy beam. The color variation from black to white indicates α varying from 0° to 180°. b, c Micrographs and reflected diffraction patterns under 0, 2, 45, 65, 85, and 150 s violet light irradiation, respectively. The chirality of CLC superstructure and wavelength of incident light are labelled. All scale bars are 100 μm
