论文摘要
对数字转换器（ADC）的电子类似物正在与众所周知的位深度与带宽权衡相对。为此，一段时间以来，RF光子增强的ADC一直是感兴趣的主题。光频梳技术已被用作许多这些架构的主力。不幸的是，这样的设计通常必须努力应对互换问题，以及频率歧义问题，可能会掩盖检测到的RF信号的关键光谱信息。在这项工作中，我们通过RF光子下调器来解决这些问题，并通过利用新型混合微型Bomb / Electro-Optic Comb Design来轻松整合和现场部署。
Electronic analog to digital converters (ADCs) are running up against the well-known bit depth vs bandwidth tradeoff. Towards this end, RF photonic-enhanced ADCs have been the subject of interest for some time. Optical frequency comb technology has been used as a workhorse underlying many of these architectures. Unfortunately, such designs must generally grapple with SWaP concerns, as well as frequency ambiguity issues which threaten to obscure critical spectral information of detected RF signals. In this work, we address these concerns via an RF photonic downconverter with potential for easy integration and field deployment by leveraging a novel hybrid microcomb / electro-optic comb design.
