A widely tuned and potentially integrated optoelectronic oscillator (OEO) is constructed based on direct modulation optical signal injection semiconductor laser. The tuning range of 9.73-21.30 GHz and the phase noise lower than -105 dBc/Hz@10 kHZ are realized. The structure of the experiment is simple and compact. If the master laser and the slave laser are integrated on the same chip, the system can be further miniaturized. If the master laser with larger modulation bandwidth is used, the tuning range of OEO can be further expanded.
