Photonic integrated signal processing device

A photonic integrated circuit (100) for performing optical transient computing on an RF-modulated optical carrier signal (106), a signal processing device (110) comprising the same, and a related processing method. The photonic circuit comprises at least two optical signal processing units (101), each including a filter device (103) and a delay element (102) for providing a delayed feedback signal to the filter device. The group delay induced by the delay element is in the range from 1 ps to 100 ps and the 3 dB bandwidth of the filter band is less than the inverse of the group delay. The delay element is adapted to spectrally align at least a portion of the filter band with a resonance in the feedback signal and center frequencies of filter bands are offset between 1 GHz and 100 GHz to allow filtering of different portions of the modulated carrier signal spectrum. The signal processing device has a trainable readout circuit (117).
