We propose and demonstrate a novel method for a radio-frequency photonic arbitrary waveform generator based on a tunable, multiwavelength pulse sequence and wavelength-to-time mapping induced by fiber chromatic dispersion. We simulate and experimentally demonstrate the generation of an arbitrary waveform and obtain burst single-tone, frequency modulation, and phase modulation signals. We also analyze the potential and primary limitations in the proposed architecture.
