Latest Patents
Fredrik Lidén holds a patent for his invention titled "Wavelength control in optical WDM systems." This patent addresses the issue of wavelength drift in optical WDM systems, which can disrupt traffic signals if not promptly identified and corrected. The invention proposes a method to detect wavelength drift by measuring temperature differences at the demultiplexer for each channel. By analyzing these temperature differences, the system can determine whether an individual channel is drifting in wavelength and implement corrective measures. This detection and correction can occur during normal operation without affecting traffic flow, ensuring optimal performance in optical communication systems.
