Oki, Kotura to Collaborate on Components

Facebook X LinkedIn Email
A 10 Gb/s receiver based on VOA-APD (variable optical attenuator-avalanche photodiode) technology for metropolitan area network applications will be the first product resulting from a collaboration between Oki Optical Components and Kotura Inc., the companies announced recently. Oki, a supplier of optical and integrated circuit components for Ethernet and telecommunication applications, and Kotura, a provider of silicon photonic components, said the silicon photonics VOA enables the 10-Gb receiver, which will be introduced later this year, to support a variety of new applications. Kotura's components are used in communications, computing, sensing and detection.

Glossary
avalanche photodiode
A device that utilizes avalanche multiplication of photocurrent by means of hole-electrons created by absorbed photons. When the device's reverse-bias voltage nears breakdown level, the hole-electron pairs collide with ions to create additional hole-electron pairs, thus achieving a signal gain.
metropolitan area network
A cable backbone used to interconnect local area networks at various sites (corporate offices and factories, for example) in a given region. Optical fiber is well-suited to the transmission of both data and voice over such a network.
photonics
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...
