Hawthorn Photonics, a US-based photonics group focused on enabling the next generation of innovation in non-linear optics, is pleased to announce that AdvR Inc. is joining the group as part of a strategic expansion of its capabilities and global footprint. This move brings together AdvR’s people, products, and technological expertise in non-linear optical devices and quantum photonics with Covesion Ltd, another Hawthorn company specializing in precision MgO:PPLN technologies, creating a powerful, integrated platform for scientific and commercial photonics solutions.

Both Covesion and AdvR have decades of experience pioneering their respective technologies.

AdvR brings a rich foundation of technical innovation in non-linear optics, using advanced materials such as potassium titanyl phosphate (KTP), lithium niobate (LN), magnesium-doped lithium niobate, and thin film lithium niobate (TFLN). The company’s diverse 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.

Covesion has established itself as a world leader in magnesium-doped, periodically poled lithium niobate (MgO:PPLN) technology, offering cutting-edge products and exceptional technical support. Its solutions cater to a wide range of applications including lasers, scientific instrumentation, quantum technology, aerospace, and environmental sciences.

Together, these two companies will serve a broader base of scientific and commercial customers with expanded capabilities and solutions engineered for the future. The combined product portfolio spans both free-space and fiber-based devices, offering high-performance phase modulators, entangled photon-pair sources, and customized frequency conversion solutions.
