Abstract
An optical phased array device, which can flexibly set the light splitting weight and has good scalability, includes a light splitting network, phase shifters, and emission units. Among them, the light splitting network of the device can set the optical power weight of the array element freely and has good scalability. The light splitting network of optical phased array consists of a series of basic elements, each of which can realize uniform or non-uniform light splitting of N channels. The light splitting network adopts a tree topology. The tree network structure can be freely designed, and the components used by the network nodes can also be freely selected. By freely designing the structure of the light splitting network and the components used by each node, the optical output distribution of the network can be set, so that the far field distribution of the optical phased array can be optimized.
