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.
