Enlightened by photonic reservoir computing, an emerging bio-inspired approach for time-dependent information processing, we present a novel concept for realization of real-time Fourier transformation, i.e., frequency-to-time mapping (FTM), of temporal waveforms based on a coherently driven passive fiber cavity with a frequency resolution of 25 MHz and extremely simple structure.
