提出了一种基于自注入锁定单片双模反馈放大激光器（DM-AFL）的宽调谐光电子振荡器（OEO），并进行了实验验证。在所提出的OEO结构中，DM-AFL用作有源可调谐微波光子滤波器（MPF）。通过调节AFL放大器部分的注入电流，实现了32 ~ 41 GHz范围内的可调谐微波输出，并在距载波10 kHz处实现了低于-97dBc/Hz的单边带相位噪声。
A widely tunable optoelectronic oscillator (OEO) based on a self-injection-locked monolithic dual-mode amplified feedback laser (DM-AFL) is proposed and experimentally demonstrated. In the proposed OEO structure, the DM-AFL functions as an active tunable microwave photonic filter (MPF). By tuning the injection current applied on the amplifier section of the AFL, tunable microwave outputs ranging from 32 to 41 GHz and single sideband phase noises below -97 dBc/Hz at 10 kHz offset from the carriers were realized.
