Title: Photonic time-domain electromagnetic signal generator and system using the same

Abstract: A photonic waveform generator and system is described. The photonic waveform generator is used in produce an electrical pulse having arbitrarily controllable temporal characteristics in a Fourier transform (FT) pulse shaper or a direct space-to-time (DST) photonic generator. The electrical pulse signal may be used in a radar, a telecommunications system or other electrical apparatus where the spectral and temporal characteristics of the signal are be optimized with respect to specific system needs, such as spectral occupancy, peak-to-average power, minimum pulse duration, target-to-clutter ratio, target type discrimination, and the like.
