Beam scanning lasers are required for systems for smart mobility, object recognition, and adaptive illuminations. The authors demonstrate dually modulated photonic crystals, wherein the positions and sizes of the photonic-crystal lattice points are modulated simultaneously, to achieve mechanical-free, 2D beam scanning.
