Following its acquisition by Hawthorn Photonics, nonlinear optics and quantum photonics instruments developer AdvR Inc. will merge with Hawthorn portfolio company Covesion Ltd. The combination of AdvR and Covesion significantly expands group capabilities across a range of nonlinear optical materials, as well as enhancing the group’s presence in North America through AdvR’s established base in Bozeman, Mont., according to a press release.

The combined product portfolio will span both free-space and fiber-based devices, to offer high-performance phase modulators, entangled photon-pair sources, and customized frequency conversion solutions.

Covesion specializes in magnesium-doped, periodically poled lithium niobate technology. Its solutions support applications including lasers, scientific instrumentation, quantum technology, aerospace, and environmental sciences. Covesion’s presence in the U.K. will enable the AdvR product range to gain greater access to European and Asian markets.

AdvR brings a foundation of technical innovation in nonlinear optics, using advanced materials such as potassium titanyl phosphate, lithium niobate, magnesium-doped lithium niobate, and thin film lithium niobate. The company’s product range includes high-efficiency frequency converters, phase modulators, and sources of entangled photon pairs, supporting advanced research and commercial deployment across quantum technologies, atomic physics, and other sensing applications.
