Silicon chip with a tiled array

Caption

A silicon chip with a tiled array of serpentine optical phased array (SOPA) tiles. The 32 tiles in the 8-by-4 array have slightly differing grating designs, showing here two matching pairs of tiles "lighting up" at this viewing angle. Drawn superimposed are beams from two matching tiles and the far field beam interference pattern demonstrating tiled beam forming.
