英文摘要	A 1??4 and a 1??6 fiber-type optical phased array with PZT phase shifters have been implemented respectively. Fibers are adopted as transmission paths and emitting antenna in the optical phased array system. By using the feedback optimization we have 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 have proposed for optimization, 1-D beam forming and beam steering in a short period of time have been observed. Compared with the 2??2 fiber-type optical phased array experiment we have done before, the beams get much narrower and grating lobes are suppressed to some extent. Moreover, the effect of the ambient temperature variation on the stability of two-fibers interference is primarily studied.; EI; 0
