Abstract: An optical device includes an array of unit optical elements. Each of the unit optical elements includes a plurality of amplitude adjustment (AA) elements, each of the plurality of AA elements configured for processing one of different phases of an optical signal; an optical antenna, and a combining mechanism for optically coupling the plurality of AA elements to the optical antenna. The optical device also includes a controller coupled to the plurality of AA elements, the controller configured for generating control signals for the plurality of AA elements according to a target optical beam pattern.

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.
