Abstract :
A novel approach to achieving photonically assisted microwave frequency twelvetupling with large frequency tunability is proposed and demonstrated. The frequency twelvetupling is realized through a joint operation of polarization modulation, four-wave mixing, and stimulated-Brillouin-scattering-assisted filtering. The key significance of the technique is that the system is capable of realizing simple frequency tuning over a wide frequency range. An experiment is performed. An electrical signal with a frequency that is tunable from 48 to 132 GHz is generated.
