1. An optical device, comprising:
a first array of optical emitters, which are disposed on a semiconductor substrate and configured to emit respective beams of optical radiation, and which comprise respective spot-size converters; and
a second array of micro-optics positioned in alignment with the respective beams of the optical emitters and arranged to condition phases of the respective beams so that different ones of the respective beams are transmitted with different phase qualities,
wherein the respective spot-size converters are mutually non-parallel, so as to emit the respective beams in respective, non-parallel directions.
