论文摘要
我们报告了基于集成的KERR微型炸弹源的光子射频（RF）分数差异。微型炸弹源的自由光谱范围（FSR）为49 GHz，生成了大量的梳子线，这些梳状线是差异化因子的高性能多波长源。通过根据计算出的TAP权重编程和塑造梳子线，在15.49 GHz的宽RF操作带宽上可实现0.15至0.90的任意分数订单。我们通过实验表征频域的RF振幅和相位响应以及具有高斯脉冲输入的时间响应。实验结果表明了与理论的良好一致性，证实了我们对具有广泛处理带宽，高可重构性的高性能分数方法的有效性，并有可能大大降低大小和成本。
We report a photonic radio frequency (RF) fractional differentiator based on an integrated Kerr micro-comb source. The micro-comb source has a free spectral range (FSR) of 49 GHz, generating a large number of comb lines that serve as a high-performance multi-wavelength source for the differentiator. By programming and shaping the comb lines according to calculated tap weights, arbitrary fractional orders ranging from 0.15 to 0.90 are achieved over a broad RF operation bandwidth of 15.49 GHz. We experimentally characterize the frequency-domain RF amplitude and phase responses as well as the temporal responses with a Gaussian pulse input. The experimental results show good agreement with theory, confirming the effectiveness of our approach towards high-performance fractional differentiators featuring broad processing bandwidth, high reconfigurability, and potentially greatly reduced size and cost.
