All-Optical Regenerators

Technology Benefits

Low signal to noise ratio Highly scalable Amenable to Mass production

Technology Application

Boost optical signal strength Send data over longer distances with reduced introduction of noise

Detailed Technology Description

Researchers at the University of California, Davis have developed an all-optical regenerator based on a Mach-Zehnder interferometer. The device is a novel solution to the old problem of optical signal strength dissipation over long distances. It resolves this issue by receiving weak signals, analyzing the data, and regenerating a new optical carrier to be further transmitted. The device does not rely on flawed amplification techniques that magnify not only the signal but also the background noise. Furthermore, it's all-optical nature eliminates the need for conversion of the optical signal to electrical and back. This has huge advantages over other optical-electrical regenerators because it can be easily scaled to large networks, and the simplicity of the design allows this technology to be implemented on a single integrated chip.
