摘要： The present invention relates to a radiofrequency oscillator comprising an optical resonator being a ring waveguide allowing the propagation of a first wave in a first direction and of a second wave in a second direction, the second direction being opposite to the first direction, and the resonator comprising an active optical medium generating a first optical line from the first wave and a second optical line from the second wave, the resonator being in contact with a part made of a material featuring a magneto-optic effect, an applier of external magnetic field of adjustable intensity on the resonator generating a frequency offset between the first wave and the second wave, and a processing circuit converting the beat between the two optical lines in a radiofrequency signal.
