Abstract
In one aspect, a system that provides a lens-integrated reconfigurable radiating source capable of two-dimensional continuous beam steering is disclosed. The system can include a silicon (Si) chip that further comprises a two-dimensional (2D) array of pixel sources/unit cells, wherein each unit cell in the 2D array includes an on-chip antenna for radiating power. The system further includes Si lens coupled to the silicon chip for controlling a directivity of a radiation beam generated by the chip. Note that the unit cells in the 2D array of unit cells can be independently activated to generate high-directivity radiation beams in a discrete set of firing angles. Moreover, the 2D array is configured to effectuate injection locking between adjacent unit cells in the 2D array when the adjacent unit cells are turned on simultaneously, wherein the injection locking effectuates a coherent radiation beam that can be continuously steered within a scanning range with fine resolution.
