论文摘要
我们报告了使用连贯的微型梳子源的宽带射频（RF）通道仪，最多92个通道。由49 GHz微环谐振器（MRR）产生的孤子晶体微型炸弹被用作多波长源。由于其超低梳子间距，C频段中最多可提供92个波长，可提供宽阔的操作带宽。另一个高Q MRR用作被动光学周期过滤器，以121.4 MHz的高分辨率将RF光谱切成镜头。我们在实验中实现了8.08 GHz的瞬时RF操作带宽，并通过热调谐验证最高17.55 GHz的RF通道化。我们的方法是朝着单层集成的光子RF接收器迈出的重要一步，其复杂性，大小和前所未有的性能，这对于从宽带模拟信号处理到数字兼容信号检测的宽RF应用非常重要。
We report a broadband radio frequency (RF) channelizer with up to 92 channels using a coherent microcomb source. A soliton crystal microcomb, generated by a 49 GHz micro-ring resonator (MRR), is used as a multi-wavelength source. Due to its ultra-low comb spacing, up to 92 wavelengths are available in the C band, yielding a broad operation bandwidth. Another high-Q MRR is employed as a passive optical periodic filter to slice the RF spectrum with a high resolution of 121.4 MHz. We experimentally achieve an instantaneous RF operation bandwidth of 8.08 GHz and verify RF channelization up to 17.55 GHz via thermal tuning. Our approach is a significant step towards the monolithically integrated photonic RF receivers with reduced complexity, size, and unprecedented performance, which is important for wide RF applications ranging from broadband analog signal processing to digital-compatible signal detection.
