A kind of wideband frequency-doubling signal generation based on optoelectr onic oscillator (OEO) is demonstrated in this paper.The radio frequency (RF) source is modulated on the optical signal wi th the first Mach-Zehnder modulator (MZM).The first MZM is biased at the minimum transmission point (MITP) to eliminate the －1and +1side bands.The optical signal is sent to the second MZM and the optoelectronic loop which consists of the single mode f iber (SMF),photodetector (PD) and RF amplifier.The frequency-doubling signal is generated by the PD,the frequency stability of the generated signal is determined by the RF source,and the phase noise is controlled by the optoelectronic loop. The generation of the wideband frequency-doubling signal is realized with a single experiment structure.In the experiment,C band and X band signals can implement frequency doubling with the system and the phase noise of the generate d signal is lower than －102dBc/Hz at 10kHz.
