摘要
We demonstrate an all-fiber-based photonic microwave generation with 10^(-15) frequency instability.The system consists of an ultra-stable laser by optical fiber delay line,an all-fiber-based"figure-of-nine"optical frequency comb,a high signal-tonoise ratio photonic detection unit,and a microwave frequency synthesizer.The whole optical links are made from optical fiber and optical fiber components,which renders the whole system compactness,reliability,and robustness with respect to environmental influences.Frequency instabilities of 3.5×10^(-15) at 100 s for 6.834 GHz signal and 4.3×10^(-15) at 100 s for9.192 GHz signal were achieved.
