The article highlights a promising direction for high-speed signal transmission in wireless optical communication systems, namely, the use of optical antennas. Unlike fiber-optic systems which are sufficiently advanced today, today only one patent and one work are performed to describe the optical antenna array, which describes the optical antenna array for transmitting the optical signal in telecommunication networks. An important task in creating the antenna is selecting intelligent material to control the radiation pattern. The main physical foundations of optical antenna array have been described. The antenna array is based on the mirror system and lens system. To provide the necessary phase shift, two kinds of structures are proposed: of lithium niobate and of ferrite-garnet. The main analytical expressions describing system behavior are found for the first time.
