Abstract
An optical phased array comprises a substrate layer having a substantially planar surface, a plurality of emitters on the surface of the substrate, and at least one cladding layer over the emitters. A plurality of optics components coupled to the cladding layer is located a predetermined distance away from the emitters, with the optics components in optical communication with the emitters. The optics components comprise a first set of optics configured for angular correction of light beams emitted from the emitters, and a second set of optics separated from the first set of optics, the second set of optics configured for divergence enhancement of the light beams transmitted from the first set of optics. Alternatively, the optics components comprise a combined set of optics configured for angular correction of light beams emitted from the emitters, and for divergence enhancement of the light beams transmitted from the combined set of optics.
