Atomic clocks

We develop atomic clocks based on rubidium hot vapor cells, transferring the stability of their atomic transitions onto a clock signal that serves as a stable frequency reference. Our portfolio includes:

• Miniature microwave atomic clocks optimized for low size, weight, and power consumption. They are enabled by our patented MEMS rubidium vapor cells, our physics package platform for miniature atomic devices, and our application-specific integrated circuits (ASICs).

• Compact optical atomic clock offering uninterrupted performance in a rack-compatible format. The all-optical operating principle enables new applications requiring high robustness and resilience.

Our roadmap focuses on pushing performance while preserving compactness and manufacturability, enabling deployment across space systems, terrestrial infrastructures, and scientific instrumentation.
