Dually modulated photonic crystals enabling high-power high-beam-quality two-dimensional beam scanning lasers
Abstract
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.
