We propose a novel all-optical true-time-delay regeneration technique that is well suited for control of phased-array antennas with time-delay beam steering. Using coherent transients, this versatile technique has the ability to regenerate a variable delay onto an optical waveform of arbitrary shape and high bandwidth. We performed simulations indicating that future research could extend the delay resolution to the subpicosecond regime. We also present proof-of-concept experimental results for a true-time-delay regenerator combined with signal processing.
