MILLIMETER-WAVE CARRIER GENERATION BY OPTICAL FREQUENCY MULTIPLICATION USING STIMULATED BRILLOUIN SCATTERING AND FOUR-WAVE MIXING

摘要

We introduced a method to generate an optical millimeter wave (MMW) carrier based on stimulated Brillouin scattering (SBS) and four-wave mixing (FWM). By placing two single mode fibers and a semiconductor optical amplifier (SOA) along the bidirectional loop, we were able to implement the process. In particular, by combining SBS and FWM effects during bidirectional transmission, we effectively obtained a MMW carrier through multiple sidebands amplified by two optical nonlinearities. During experimentation, the generated MMW carrier displayed a narrow linewidth of 314 Hz at a frequency of 54.26 GHz, as well as phase noise of -81.50 dBc/Hz at 10 kHz offset.
