Lasers precisely stabilized to known transitions between energy levels in simple, well‐isolated quantum systems such as atoms and molecules are essential for a plethora of applications in metrology and optical communications. The implementation of such spectroscopic systems in a chip‐scale format would allow to reduce cost dramatically and would open up new opportunities in both photonically integrated platforms and free‐space applications such as lidar. Here the design, fabrication, and experimental characterization of a molecular cladded waveguide platform based on the integration of serpentine nanoscale photonic waveguides with a miniaturized acetylene chamber is presented. The goal of this platform is to enable cost‐effective, miniaturized, and low power optical frequency references in the telecommunications C band. Finally, this platform is used to stabilize a 1.5 µm laser with a precision better than 400 kHz at 34 s. The molecular cladded waveguide platform introduced here could be integrated with components such as on‐chip modulators, detectors, and other devices to form a complete on‐chip laser stabilization system.

基于乙炔的电信频段芯片级光频率基准
在简单、隔离良好的量子系统（如原子和分子）中，激光器精确地稳定在已知能级之间的跃迁，对于计量学和光通信中的大量应用至关重要。以芯片级格式实施此类光谱系统将大大降低成本，并将为光子集成平台和激光雷达等自由空间应用开辟新的机会。本文介绍了基于蛇形纳米级光子波导与小型乙炔室集成的分子包层波导平台的设计、制造和实验表征。该平台的目标是在电信 C 频段实现经济高效、小型化和低功率的光学频率参考。最后，该平台用于稳定 1.5 µm 激光器，其精度在 34 秒时优于 400 kHz。这里介绍的分子包层波导平台可以与片上调制器、探测器和其他设备等组件集成，形成完整的片上激光稳定系统。
