Abstract
An optical device includes a row of optical units, each of the optical units comprising an antenna element and an associated phase shifting element, a first optical power splitter optically coupled to a first optical input/output element, and a first plurality of boundary adjustment elements. In the optical phased array, each of the first plurality of boundary adjustment units optically couples the first optical power splitter to different sub-rows of the row of optical units, and each of the plurality of boundary adjustment elements include a sub-row amplitude adjustment element and a sub-row phase adjustment element.
