IPG Buys 100 BT Patents
Feb 2008
OXFORD, Mass., Feb. 26, 2008 -- IPG Photonics Corp., an Oxford, Mass.-based maker of fiber lasers and amplifiers, announced today it has purchased more than 100 US patents, and more than 340 foreign counterparts, by acquiring a photonics patent portfolio from British Telecom.

The acquired patents involve research by British Telecom in the photonics field dating to the 1990s in the fields of optical fiber lasers and amplifiers, semiconductor devices, integrated optics, fiber gratings, high-speed systems and optical networking. IPG said it is particularly interested in early patents for single-mode lasers.

“With the purchase of these important patents, IPG’s intellectual property portfolio is unparalleled in the fiber laser field,” said IPG Photonics CEO Valentin P. Gapontsev. “These patents complement our strong IP portfolio, including the growing number of pending-patent applications that we already have.”

integrated optics
A thin-film device containing miniature optical components connected via optical waveguides on a transparent dielectric substrate, whose lenses, detectors, filters, couplers and so forth perform operations analogous to those of integrated electronic circuits for switching, communications and logic.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
