All-Optical Regenerators

Tech ID: 11239 / UC Case 2003-538-0


Reconfigurable multi-channel all-optical regenerators.

Full 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.
