"microscopic curved structures simultaneously redirect thousands of beams upward/ outward from chip... structures form because device made from silicon nitride/ aluminum nitride that expand differently during fabrication/ bending when cooled... AR glasses' displays, compact LiDAR sensors, faster laser-based 3D printing, large-scale quantum computers laser controlling millions qubits... full-color images half size grain salt. 10s of 1000s tiny pixels in space where smartphone displays have only a few"
