摘要
Liquid-crystal display technology is ubiquitous, but these materials can also be used to make electrically tunable components for optics and photonics. The authors demonstrate voltage control of the wavelength of flexoelectric domains in a transmissive diffraction grating, which enables dynamic light steering. They prove that the mechanism of pattern onset differs from that of switching between flexodomain states, and they explain the surprising finding that the response to increasing voltage is much slower than that to decreasing voltage.
