Abstract

A 2×2 and a 1×4 fiber-type optical phased array with PZT phase shifters have been implemented. Fibers are adopted as transmission paths and emitting antennas in the optical phased array system. By using the feedback optimization we had proposed before, the inaccuracy of fiber length is overcome. By adjusting the phase shift of each PZT phase shifter repeatedly according to the algorithm we had proposed for optimization, 1-D and 2-D beam forming and beam steering in a short period of time have been observed respectively. Moreover, a 1×6 fiber array is also tried. Although the interference is not stable enough, much narrower beams are achieved.
