Latest Patents
Yang Li holds a patent for a groundbreaking method titled "Fiber sensing by monitoring polarization function of light on supervisory path of cables." This innovation employs a supervisory system of undersea fiber optic cables to detect earthquakes and other disturbances by monitoring the polarization of interrogation light. The method emphasizes the importance of the polarization transfer matrix, allowing for the isolation of disturbance locations by analyzing eigenvalues. Experimental results have demonstrated the capability to monitor disturbances affecting signal polarization on a span-by-span basis using High Loss Loop Back (HLLB) paths. The technique shows that by measuring the polarization rotation matrix and determining the polarization rotation angle, disturbances can be identified with a remarkable 35 dB extinction, regardless of the disturbance's magnitude or the number of affected spans.
