A dispersive optical phased array for two-dimensional scanning. Interuniversitair Micro-Electronica Centrum vzw
A dispersive optical phased array (500) for two-dimensional scanning. The array comprises M antenna blocks (520) positioned adjacent one another. The M antenna blocks comprise a plurality of antennas (540) positioned adjacent one another and a plurality of delay lines (550) to couple a coherent source signal (510) to each of the antennas within the block, each delay line having an optical path length. Each of the M antenna blocks acts as a dispersive phased array. The antenna blocks are arranged such that the blocks form a larger phased array where the antennas between the blocks are only in ...
