To overcome the beam squint in wide instantaneous frequency, we review a number of system level optical controlled phase array antenna (OCPAA) for beam forming. The optical delay network based on fiber device in terms of topological structure of N-bit optical switch, fiber grating, high-dispersion fiber, vector-sum technology is discussed, respectively. At last, integrated circuit is simply summarized.
