AI Technical Summary
Technical Problem
Existing methods for transmitting optical signals over long distances suffer from phase and frequency instabilities due to length changes in the transmission path, and the use of amplifiers violates reciprocity, leading to parasitic lasing and other issues.
Method used
A device and method utilizing interferometer arrangements with detectors and control loops to stabilize the phase of optical signals, allowing for non-reciprocal elements like optical amplifiers, and enabling phase-stable transmission over long distances with multiple destinations.
Benefits of technology
Enables phase-stable transmission of optical signals over long distances, supports multiple destinations, and allows for the use of non-linear processes, providing enhanced stability and scalability.
