Abstract
(EN)
An optical device (20A, 20B, 100, 200, 800) includes a first array of emitters (28A, 28B) disposed on a semiconductor substrate (218) and configured to emit respective beams of optical radiation. A second array (36A, 36B, 224, 808) of micro-optics (34A, 34B, 226, 802) is positioned in alignment with the respective beams of the optical emitters and arranged to condition phases of the beams so that different ones of the beams are transmitted with different phase qualities
