我们演示了一个毫米波自注入锁定（SIL）振荡器具有一个长的光延迟线作为反馈路线。在SIL振荡器中，一部分输出信号通过长光延迟线后自注入振荡器，从而实现锁定振荡和相位噪声降低。通过控制自注入功率，我们实现了30 GHz的振荡与边模抑制比大于50 dB，约18 dB的相位噪声降低在10 kHz的频率偏移。
We demonstrate a millimeter-wave self-injection-locked (SIL) oscillator having a long optical delay line as a feedback route. In the SIL oscillator, a part of output signal is self-injected into the oscillator after passing through a long optical delay line, resulting in locked oscillation and phase-noise reduction. By controlling the self-injection power, we achieve 30-GHz oscillation with a sidemode suppression ratio larger than 50 dB and about 18-dB phase-noise reduction at 10-kHz frequency offset.
