IPG acquires photonics patent portfolio from BT

High-power fiber-laser and amplifier maker IPG Photonics Corp of Oxford, MA, USA has acquired a photonics patent portfolio comprising more than 100 US patents and more than 340 foreign counterparts from British Telecom. These include patents relevant to components and systems as well as devices and techniques that are commonly used throughout the photonics industry.

The patents concern pioneering photonics research by British Telecom dating from the 1990s in the fields of optical fiber lasers and amplifiers, semiconductor devices, integrated optics, fiber gratings, high-speed systems and optical networking.

“These patents complement our strong IP portfolio, including the growing number of pending patent applications that we already have,” says CEO Dr Valentin P. Gapontsev.

Of particular note are early patents covering single-mode lasers, says IPG.
