Frequency-quadrupling microwave signal generation based on Brillouin-assisted optical notch filter

Abstract

A novel technique to generate frequency quadrupling microwave signal is proposed and experimentally demonstrated based on a Brillouin-assisted optical notch filter (BAOF). The intensity modulated optical signal is firstly working at the maximum transmission point to suppress the first order sidebands. Microwave signals at the frequency corresponding to four times of the fundamental tone are successfully generated.
