30-GHz millimeter-wave carrier generation with single sideband modulation based on stimulated Brillouin scattering
摘要
Abstract
A new technique to generate a 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 cartier 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 a 3-dB bandwidth of 10 kHz.关键词
