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.

The invention relates to the field of optical parametric oscillators (OPO), especially to an essentially vertical monolithic system (S) for parametric conversion from a pump wave with a pump wavelength, said system comprising at least two resonant cavities (). Said cavities are coupled by at least one coupling mirror (), at least one of the cavities comprising an active non-linear medium, and the at least one coupling mirror being arranged in such a way that the parametric frequencies associated with the pump wavelength are located in the stop line of the at least one mirror for an injection direction of the pump wave essentially according to the axis of the system.
