30-GHz millimeter-wave carrier generation with single sideband modulation based on stimulated Brillouin scattering
基于受激布里渊散射的30GHz毫米波单边带调制生成技术

A new technique to generate millimeter(mm)-wave carrier of 32.57 GHz (fLO=10.85 GHz) with Single Sideband Modulation (SSB) for Radio-over-Fiber (RoF) systems is experimentally demonstrated by using Stimulated Brillouin Scattering (SBS). The SSB is realized by directly amplifying the 3rd sideband of the modulated optical carrier in the process of SBS. The pump wave is provided through a Double Brillouin Scattering Frequency Shifting configuration. The use of the same laser source to generate the pump wave ensures the stability of the mm-wave generation system since the relative frequency shift between them can be eliminated. In addition, the mm-wave carrier obtains an RF power gain of 21 dB with the SBS amplification and 3-dB bandwidth of 10 kHz.
