An injection-phase locked optoelectronic oscillator based on injection locking and phase-locked loop techniques was proposed. Utilizing the injection locking to reduce the close-in phase noise and increase the side-mode suppression ratio. Using the phase-locked loop to improve the frequency stability of the optoelectronic oscillator by detecting the phase between the output signal of the optoelectronic oscillator and the external injection source and also to furtherly improve the close-in phase noise performance. The experimental results show that, when the electrical filter′s center frequency and 3 dB bandwidth are 9.5 GHz and 20 MHz, single mode oscillation at 9.5 GHz is realized by a 6 km-fiber single loop injection-phase locked optoelectronic oscillator. When the injection locking bandwidth is 1.98 kHz, the phase noises of the optoelectronic oscillator′s output signal are about -125 dBc/Hz at 1kHz offset frequency and -147 dBc/Hz at 10kHz offset frequency, the SMSR is higher than 70 dB, and the Allan deviations are about 1.37×10-11@1s and 1.22×10-11@1000s.
