The invention discloses a two-dimensional optical phased array. The two-dimensional optical phased array can be applied to multiple technical fields, such as laser radar, biomedical imaging, holographic imaging and ultra-high data rate communication. Array elements of the two-dimensional optical phased array are a set of point light sources with the same frequency, the phased array takes one of the array elements as the center of the circle, and the other array elements are evenly divided into a plurality of groups; each group of array elements and the center of the circle form a radial linear array, and the linear arrays have the same structures and are distributed at equiangular intervals in the circumferential direction. The structure of the two-dimensional optical phased array has the characteristics of a circular shape, equiangular intervals, high symmetry, compact spatial distribution of the array elements and the like, and therefore, the two-dimensional optical phased array has the advantages of low in processing difficulty, strong in inhibitive capability of grating lobes, large in two-dimensional scanning range and the like; besides, based on a non-uniform array element distribution grating lobe inhibiting technique, the phases of the array elements of the phased array are controlled so as to achieve beam formation and imaging, and the grating lobes and a multi-level effect can be effectively inhibited; in addition, single beam formation is achieved, and meanwhile the beam scanning resolution is high.
