Abstract

Lasers precisely stabilized to known transitions between energy levels in simple, well-isolated quantum systems such as atoms and molecules are highly desired for myriad of applications ranging from precise measurements to optical communications. The implementation of such spectroscopic systems in a chip-scale format would allow for dramatically reduced cost and would likely open up significant new opportunities in both photonically-integrated platforms and free-space applications such as lidar. Here, we design, fabricate, and experimentally demonstrate a new platform based on chip-scale integration of serpentine photonic nanoscale waveguides with a miniaturized acetylene chamber potentially enabling cost effective, miniaturized and low power optical frequency references in the telecommunications C band spectral range (1530 nm - 1565 nm). We have used this platform to stabilize a telecom laser with a precision better than 400 kHz at 34 s. This small and portable chip-scale molecular cladded waveguide can be integrated with advanced components such as on-chip modulators, detectors, and other devices to form a complete locking system on-chip.
