The knowledge of the exact frequency of an optical source has always been one of the ultimate goals in optics. Since the discovery of the laser, complex systems have been developed to address this challenge. That effort reached a significant milestone with the advent of the femtosecond laser frequency comb that reduced the system size from an entire lab down to the bench‐top. That spurred interest in the development of integrated optical frequency synthesizers that can generate precisely different optical frequencies on demand and can be deployed widely. In this work, such an optical frequency synthesizer using supercontinuum waveguide and second harmonic generator on silicon photonics platform is demonstrated. Integrated silicon photonics based tunable continuous wave laser is phase‐locked to a microwave reference, to synthesize absolute optical frequencies in the telecom band. A relative frequency instability of 1 × 10−12 at 1 s level is achieved by utilizing an integrated self‐referencing scheme that exploits the strong 3rd order and electric‐field‐induced 2nd order nonlinearities of silicon waveguides. With this work, an all on‐chip silicon photonics based frequency synthesizer seems promising for mass production of next generation broad‐band coherent optical communication systems, spectroscopic, detection, and ranging systems and future integrated quantum systems with Hz‐level precision.

硅光子光学频率合成器
了解光源的确切频率一直是光学的最终目标之一。自从发现激光以来，已经开发出了复杂的系统来应对这一挑战。飞秒激光频率梳的出现使这项工作达到了一个重要的里程碑，它将整个系统的规模从整个实验室减小到了台式。这激发了对集成光频率合成器的开发的兴趣，该合成器可以按需生成完全不同的光频率，并且可以广泛部署。在这项工作中，展示了一种在硅光子平台上使用超连续谱波导和二次谐波发生器的光频率合成器。基于集成硅光子学的可调谐连续波激光器被锁相到微波参考，合成电信频段中的绝对光频率。相对频率不稳定性为1×10通过利用集成的自参考方案，可实现1 s级别的-12，该方案利用了硅波导的强三阶和电场诱导的二阶非线性。通过这项工作，基于全片上硅光子学的频率合成器似乎有望大规模生产下一代宽带相干光通信系统，光谱，检测和测距系统以及具有Hz级精度的未来集成量子系统。
