An electro-optical conversion system including an opto-mechanical conversion device which includes a ring cavity formed by an optical waveguide which extends along an annular closed curve, a micromechanical resonator that comprises at least one microbeam, and a zipper type element integrated into the ring cavity, the zipper type element including a first arm made on a portion of the ring waveguide and a second arm made on the microbeam. The conversion system also includes a capacitor with first and second electrodes separated by a gap which varies when the microbeam oscillates.

Electro-optical conversion system

An electromechanical conversion device includes a resonant electrical circuit comprising an inductance and a capacitor, the capacitor including at least a first electrode and a second electrode; and a mechanical oscillator including at least one microbeam formed in a membrane, the first and second electrodes being located side by side and the first electrode of the capacitor being located on a face of the microbeam so that the electrical capacitance of the capacitor varies when the mechanical oscillator oscillates; device wherein the inductance includes an electric track of very low thickness made on the membrane and made of a superconductive material chosen so as to obtain an electric track with a high kinetic inductance.
