Abstract

At present, the deficiency of large size and bad environmental adaption etc. hinders the engineering application of optoelectronic oscillator (OEO). By hybrid integration of photonic chips and electronic ones, a significantly miniaturized OEO with low phase noise is achieved and presented in this paper. Meanwhile, a frequency stabilization configuration based on hybrid optoelectronic phase locking is designed to improve the capability of environmental adaptation. Therefore, the OEO frequency can follow the external reference signal at real time and keep high stability as well. The performance for the OEO prototype with a volume of Φ100 mm×200 mm is investigated in detail. The spur suppression is over 70 dBc for the oscillation frequency of 10 GHz. And the phase noise of -145.9 dBc/Hz@10 kHz is reached.
