“…A wavelength reference at 780 nm based on this approach was recently demonstrated 274 with a stability of 10 À11 at integration times beyond 10 s. In this design, transit-time broadening was reduced using grating output couplers 275 and a photonic extreme mode converter that generated a $50 lm output beam from a sub-micron mode in the waveguide.…”

We present an experimental scheme performing scalar magnetometry based on the fitting of Rb D 2 line spectra recorded by derivative selective reflection spectroscopy from an optical nanometric-thick cell. To demonstrate its efficiency, the magnetometer is used to measure the inhomogeneous magnetic field produced by a permanent neodimuim-iron-boron alloy ring magnet at different distances. The computational tasks are realized by relatively cheap electronic components: an Arduino Due board for the external control of the laser and acquisition of spectra, and a Raspberry Pi computer for the fitting. The coefficient of variation of the measurements remains under 5% in the magnetic field range of 40 -200 mT, limited only by the size of the oven and translation stage used in our experiment. The proposed scheme is expected to operate with a high measurement precision also for stronger magnetic fields (> 500 mT), in the hyperfine Paschen-Back regime, where the evolution of the atomic transitions can be calculated with a high accuracy.

“…Furthermore, we will improve the coupling stability by permanently attaching the fibers to the waveguide, e.g., following the approach reported in ref. [26] where fibers were glued to the chip. Finally, we will enhance the temperature stabilization of the apparatus by using a better control system and a larger thermal mass.…”

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.
