Problem
High‑performance photonics applications such as quantum sensing, atomic clocks, and terahertz communications require oscillators with ultra‑narrow linewidth, high spectral purity, and long‑term stability. Existing laboratory‑scale sources are bulky and cannot be miniaturised without degrading signal quality, preventing these technologies from being deployed in real‑world systems.
Solution
Ultrapure creates chip‑scale signal sources that generate ultrapure waves across radio, microwave, terahertz, and optical frequencies by exploiting stimulated Brillouin scattering (SBS) in a thin‑film lithium tantalate (TFLT) platform. The integrated SBS lasers deliver ultra‑high spectral purity, low phase noise, and voltage‑controlled tuning in a compact form factor. The technology provides thermal stability and low signal loss, enabling reliable operation in field‑deployed environments. By delivering narrow‑linewidth oscillators on a silicon‑compatible platform, Ultrapure bridges the gap between laboratory prototypes and commercial products for next‑generation timing, sensing, and communication systems.
Target Audience
Primary customers are manufacturers of atomic clocks, quantum sensors, and terahertz communication equipment, as well as system integrators developing precision timing and navigation solutions for smart‑city and GPS‑free applications.
