摘　　要：基于直调光信号注入半导体激光器构建了宽调谐潜在可集成的光电振荡器(OEO),实现了9.73~21.30 GHz的调谐范围,且调谐过程中相位噪声始终小于-105 dBc/Hz@10 kHz。实验结构简单、紧凑。若将主、从激光器集成在同一芯片上,系统还可进一步小型化。若采用调制带宽更大的主激光器,OEO调谐范围还可进一步扩大。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.
