Latest Patents

One of his latest patents is a "Radio frequency oscillator and associated source and apparatus." This invention relates to a radiofrequency oscillator that comprises an optical resonator in the form of a ring waveguide. This design allows for the propagation of a first wave in one direction and a second wave in the opposite direction. The resonator includes an active optical medium that generates two optical lines, and it is in contact with a material that exhibits a magneto-optic effect. An external magnetic field can be applied to generate a frequency offset between the two waves, with a processing circuit converting the beat between the optical lines into a radiofrequency signal.

Another notable patent is the "Device for electro-optical sampling of a microwave frequency signal." This device features a microwave transmission line that transmits a microwave signal. It includes an interruption zone that can be rendered conducting under the influence of an optical control signal, functioning as an optically controlled interrupter switch. The interruption zone contains a layer of nanostructured semiconductor material, which is strategically placed to perform the function of the interrupter switch.
