Paper Abstract
Transfering the principle of array antennas from the microwave regime into optics results in a system which permits non-mechanical steering of laser beams. The feasibility of such an optical array antenna strongly depends on the accuracy of realization because of the small wavelengths involved. Therefore we analyzed the sensitivity of optical phased array antennas to errors in subantenna phasing, positioning and aligning. Assuming independent Gaussian error distributions we determined the resulting antenna gain reductions by calculating the average reduction and upper probability limits for reductions which exceed a certain tolerable limit.
