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.
