Latest Patents
One of Ken's latest patents is a "Method and apparatus to compensate for polarization mode dispersion." This invention includes a polarization scrambler and a PMD compensation system that work together to address polarization mode dispersion in active optical fibers. The polarization scrambler alters the state of polarization of an optical signal carrying user information. The PMD compensation system measures the differential group delay and principal states of polarization, allowing it to adapt to changes in the PMD and modify the optical signal accordingly.
Another significant patent is the "Method and apparatus for recovering an optical clock signal." This clock recovery system is designed to extract an optical clock signal from an optical data signal, independent of wavelength and data rate. The system splits the optical data signal and transmits the two parts in opposite directions around a fiber loop, where they interact to recover the optical clock signal.
