摘要：

Optically controlled wide-range beam steering and spectrum scanning are demonstrated by a self-organized liquid crystal grating. The diffraction angle can be tuned around 30° upon light irradiation. In addition, a reversible spectrum scanning system can be constructed using the optical tunable grating. This highly tunable light-driven grating has great potential in light propagation control and spectroscopy applications. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
