Abstract: A polarization-tracking device having a waveguide grating that serves as a polarization splitter and an optical fiber-to-waveguide coupler. The polarization-tracking device also has an optical mixing circuit configured to receive light from the waveguide grating and a control circuit for tuning the optical mixing circuit. Based on an optical feedback signal received from the optical mixing circuit, the control circuit can configure the latter to produce two optical output signals that represent, e.g., two independently modulated polarization components of a polarization-multiplexed optical input signal or two principal states of polarization of an optical input signal that has been subjected to polarization-mode dispersion. Certain embodiments of the polarization-tracking device lend themselves to convenient implementation in a photonic integrated circuit and are configurable to provide endless polarization control.

Abstract: Timing alignment between a pulse carver (i.e., intensity modulator) and a phase modulator, e.g., in a return-to-zero (RZ) differential phase-shift keying (DPSK) optical transmitter, is monitored by filtering a signal from the transmitter and measuring the power of the filtered signal. In certain embodiments, the filter has a birefringent device (such as a polarization-maintaining fiber) and a polarizer. The polarizer may be a rotating polarizer with a rotating quarter-wave plate in front of it. In other embodiments, the filter is a periodic filter such as a Mach-Zehnder interferometer or an etalon filter. Regardless, the measured power may be used to generate control signals used to variably delay the signals that drive the phase modulator and/or the pulse carver to compensate for detected misalignment. The measured power may also be used to monitor the bit-error-rate degradation caused by timing misalignment between the pulse carver and the phase modulator.

Abstract: The present invention relates to a signal processing system for generating a nulling signal for attenuating a periodic noise component from an information signal. According to one aspect of the invention, the system includes two nested feedback networks. One network detects the phase angle and frequency of the noise component, and generates a nulling signal having a phase angle and frequency substantially equal to the phase angle and frequency of the noise component. The other network detects the amplitude of the noise component, and scales the nulling signal to have an amplitude substantially equal to the amplitude of the noise component. According to a further aspect of the invention, the system includes a combining network for attenuating the noise component by combining the information signal with the nulling signal. In this way, the invention preserves the high fidelity of the information signal except over a very narrow bandwidth, adjacent to the noise signal frequency. According to one embodiment the combining network is mechanical in nature, while according to another embodiment, the combining network is electronic in nature.
