Latest Patents
One of his latest patents is focused on a PMDC feedback arrangement for APol-DPSK. This invention provides methods and apparatus for optical polarization mode dispersion compensator (PMDC) feedback control for APol-DPSK signals. The feedback signal generator includes a delay-line-interferometer (DLI), which features a differential delay line delay (D) that differs from one bit period (Tb). In an exemplary embodiment, the DLI delay is designed to be in the range of 0.5 Tb < D < 1.0 Tb, or 1.0 Tb < D < 1.5 Tb, with a preference for 0.85 Tb or 1.15 Tb. The DLI is coupled to a single-ended detector, whose output is amplified and bandpass filtered around the frequency of half the bit rate. The filtered signal is then applied to an RF power detector to generate the PMDC feedback signal. This innovative approach ensures that the generation of the PMDC feedback signal is insensitive to any alignment of the state of polarization (SOP) of the received APol-DPSK signal with the principal state of polarization (PSP) of the transmission link. Consequently, there is no need for a polarization scrambler at the transmitter, leading to reduced complexity and cost while improving performance.
Another significant patent involves an effective control algorithm for optical polarization mode dispersion compensators. This invention includes a variable step size dithering control algorithm for polarization mode dispersion controllers (PMDCs). The dithering step size of the PCs is adjusted based on the feedback signal, which includes the degree of polarization (DOP).
