Paper Abstract

An improved Brillouin-assisted photonic microwave downconverter that features simple structure and wide frequency tunable range is experimentally demonstrated. In order to obtain higher conversion efficiency, SBS-assisted notch filter is used to suppress the carrier of phase modulated signal. Due to the SBS-assisted notch-filtering is generated by the phase modulated signal itself, which simplify the system structure effectively. Furthermore, the effective suppression of the carrier of phase modulated signal and the diminishment of the second-order Stokes wave could be achieved simultaneously by optimizing the attenuation of the variable optical attenuator, which guarantee our scheme can operate over a wide frequency range.
