About this opportunity
The Department of Energy has published a Special Notice regarding a licensing opportunity for an all-fiber automatic polarization compensation technology using ultra-sensitive detection of coexisting dim reference signals. This technology addresses the issue of polarization drift in quantum networks, where fiber transforms a transmitted signal's polarization differently depending on its environment. The objective is to provide a system that can measure and compensate polarization changes in quantum fiber networks, ensuring 100% uptime, high-bandwidth detection and correction, low-insertion loss, and negligible added noise.
The key details include a due date of October 26, 2024 for interested parties to learn more about the technology. The technology is not set aside for any particular contractor type and can be used for both quantum and classical communications applications. To participate, contractors should email partnerships@ornl.gov or call 865-574-1051 to inquire about the licensing opportunity and potential applications of the automatic polarization compensation system.
Notice text
Invention Reference Number: 202405654
Polarization drift in quantum networks is a major issue. Fiber transforms a transmitted signal’s polarization differently depending on its environment. This technology strengthens quantum networking by providing automatic polarization compensation using ultra-sensitive detection of coexisting dim reference signals. It achieves fast and complete control of the polarization of light while ensuring 100% uptime by using very weak reference signals. This new system for measuring and compensating polarization changes features a multi-axis control mechanism designed for low-loss, high-speed operation and simplicity. Combining ultra-sensitive detection with fast, low-loss polarization control avoids noise issues from reference signals, ensuring it can operate continuously without downtime.
Description
This technology is a new method for measuring and compensating polarization changes in quantum fiber networks. It benefits from combining ultra-sensitive detection with fast, low-loss polarization control, avoiding noise issues from reference signals. This ensures the system can operate continuously without downtime. This new method balances the demands of 100% up-time, high-bandwidth detection and correction, low-insertion loss, and negligible added noise. Laser reference signals can be used while still maintaining the benefits of dim reference signals detected by single-photon detectors. This helps enable 100% uptime. This system can control polarization of light through fiber at a high bandwidth, and for single-photon quantum signals without injecting significant noise.
Benefits
- Fast continuous control
- Controls polarization automatically
- Low noise
- Precise control with high bandwidth
- No downtime
- Could be used for classical communications, too, not only for quantum communications
Applications and Industries
- Quantum technologies
- Fiber internet
