ABSTRACT:
A practical means for electrically addressing the extremely large number and high density of phase shifters needed for operation of an optical phased-array beam steerer. The array of phase shifters is divided into identical subarrays which completely fill an optical aperture. All subarrays are connected electrically in parallel by electrically interconnecting corresponding electrodes of each subarray. Thus, the number of external electrical leads required for addressing the full array is reduced to the number of phase shifters in a signle subarray.
