Millimeter wave generation using Brillouin scattering in a high Q fiber ring resonator

We introduce an efficient technique to optically generate millimeter-wave sources. The technique is based on the frequency multiplication concept using high order harmonics, generated by a Mach-Zehnder modulator, combined with the Brillouin selective side band amplification process in a high Q fiber ring resonator. We demonstrate the generation of a low phase noise 65.2 GHz signal with a power level 15 dB higher than the power level usually obtained using classical frequency multiplication.
