Abstract: The present invention refers to an optoelectronic device for the detection of substances dispersed in a fluid. The optoelectronic device comprises: —a light source adapted to emit a light radiation; —an optical splitter comprising an optical input port optically coupled to said light source and a plurality of optical output ports, said optical splitter being adapted to receive a first light beam at said optical input port and to provide one or more second light beams, each transmissible from a corresponding optical output port; —a plurality of detection stages operatively coupled to said optical splitter and arranged in parallel with one other, —a plurality of control stages arranged in parallel to one another, each control stage being operatively coupled to a corresponding detection stage.

Abstract: An optical transmitting-receiving module with neural network, including a power divider which distributes an input signal to be corrected and sends it in waveguides to an optical delay component which imparts time delays to copies of the optical signal; an optical control component that weights each delayed copy with an amplitude and a phase that are electrically adjusted during a training procedure; and a coupler which recombines the N signals and a non-linear node to which a complex sum is sent at the output of the coupler.
