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.

Electromechanical conversion device and system using such a device

A traveling wave superconducting parametric amplifier is provided. The traveling wave superconducting parametric amplifier includes a chain of superconducting elements having a nonlinear kinetic inductance connected in series, said superconducting elements being deposited on a substrate. The traveling wave superconducting parametric amplifier also includes a dielectric layer of sub-micrometer thickness deposited on the substrate and covering said superconducting elements, and a conductive layer forming a ground plane deposited on top of the dielectric layer, the superconducting elements and the ground plane forming a microstrip-type transmission line. A method for producing such a traveling wave parametric amplifier is also provided.
