An optoelectronic device for extracting characteristics in analog radiofrequency signals, forming an analog input signal, the device comprising: an input module generating an optical carrier wave and performing a modulation of this carrier by the analog input signal, to form a modulated optical signal; a network of linear optical cavities optically pumped and coupled by the modulated optical signal; an optical device for measuring the measured quantities of the optical fields, these optical fields being induced by the optical signal modulated by the analog input signal; a calculation module performing a linear transformation on the measured quantities of the optical fields; to make it possible to reconstruct and extract targeted characteristics contained in the spectrum of the radiofrequency input signal, the calculation module having performed machine learning on noisy analog radiofrequency drive signals having the same targeted characteristics in order to determine parameters.
