The authors demonstrate a photonic analogue-digital converter architecture based on temporal-spectral mapping. Linearily chirped optical pulses form a quasi-continuous carrier modulated by the analogue RF signal. The signal is separated into several distinct wavelength channels for parallel demodulation and quantisation. Measurements performed on 70ps electrical signals indicate six bit resolution.
