The technology of optical phased array is well known for its flexibility, high speed and accurate beam scanning. This technology is used in the new systems of laser radar, space laser communications and other important related applications. This paper reviews the research progress of optical waveguide phased array technology and introduces the latest research progress of optical phased array based on LiNbO3, GaAs/AlGaAs, InP, and silicon-on-insulator materials in detail. We also discuss the characteristics and advantages of the optical waveguide phased array. The applications in laser scanning imaging, laser radar, laser displays, optical switches, laser printing and other military and civilian areas are discussed. Finally, the development prospect of the optical waveguide phased array technology is proposed.
