在过去十年里，微梳引发了从光通信到计量学的应用激增。尽管其部署形式多样，但大多数基于微梳的系统依赖于大量笨重的元件和设备来实现其所需的功能，这是复杂、昂贵和耗电的。相比之下，基于代工的硅光子学(SIPH)在以可扩展和低成本的方式提供多功能方面取得了显著的成功，但其现有的基于芯片的光源缺乏并行能力，这限制了SIPH的应用范围。在这里，我们将这两项技术结合在一起，使用一种高能效且操作简单的绝缘体上砷化铝微梳电源来驱动互补的金属氧化物半导体SIPH发动机。我们提出了两个重要的芯片级光子系统，分别用于光数据传输和微波光子学。提出了一种基于脉冲幅度四能级调制方案的微梳集成光子数据链路，该链路采用每秒2太比特的脉冲幅度调制方式，并采用时间延伸法构建了一个高度可重构的高集成度微波光子滤波器。微梳和SIPH集成组件的这种协同是迈向下一代全集成光子系统的关键一步。一种简单且高能效的微梳光源被用来驱动互补的金属氧化物半导体硅光子引擎，向下一代完全集成的光子系统迈进了一步。
Microcombs have sparked a surge of applications over the past decade, ranging from optical communications to metrology. Despite their diverse deployment, most microcomb-based systems rely on a large amount of bulky elements and equipment to fulfil their desired functions, which is complicated, expensive and power consuming. By contrast, foundry-based silicon photonics (SiPh) has had remarkable success in providing versatile functionality in a scalable and low-cost manner, but its available chip-based light sources lack the capacity for parallelization, which limits the scope of SiPh applications. Here we combine these two technologies by using a power-efficient and operationally simple aluminium-gallium-arsenide-on-insulator microcomb source to drive complementary metal–oxide–semiconductor SiPh engines. We present two important chip-scale photonic systems for optical data transmission and microwave photonics, respectively. A microcomb-based integrated photonic data link is demonstrated, based on a pulse-amplitude four-level modulation scheme with a two-terabit-per-second aggregate rate, and a highly reconfigurable microwave photonic filter with a high level of integration is constructed using a time-stretch approach. Such synergy of a microcomb and SiPh integrated components is an essential step towards the next generation of fully integrated photonic systems. A simple and power-efficient microcomb source is used to drive complementary metal–oxide–semiconductor silicon photonic engines, a step towards the next generation of fully integrated photonic systems.
