    Abstract: A wavelength-tracking dispersion compensator (WT-DC) tracks the wavelength of a received input signal. The WT-DC includes an input signal optical monitor, a differential detector control circuit, a temperature controller, and an input signal dispersion compensator. The monitor includes a Mach-Zehnder interferometer that matches the dispersion compensator free-spectral range or an integer sub-multiple or multiple thereof. The monitor is coupled to the differential detector control circuit that controls a temperature controller to set the temperature of the monitor and dispersion compensator. The WT-DC automatically tracks the wavelength of the input signal. In a preferred embodiment, the monitor and the dispersion compensator are integrated on the same planar lightwave circuit chip and include a half-wave plate.

    Abstract: An apparatus includes an optical wavelength-converter and a polarization splitter. The polarization splitter is configured to receive input and pump light, to direct a first polarization component of the received input and pump light to a first optical path, and to direct a second polarization component of the received input and pump light to a separate second optical path. The optical wavelength-converter has first and second optical ports. The first optical port is at an end of the first optical path. The second port is at an end of the second optical path. The wavelength-converter outputs wavelength-converted light from one of the ports in response to receiving the input and pump light at the other of the ports. The two optical paths may include polarization-maintaining optical waveguides. The polarization splitter and optical paths may be configured to transmit substantially the same pump light intensity to the two optical ports.

    Abstract: The inventors propose herein a novel band filter design for planar lightwave circuits. In one embodiment of the present invention, the band filter includes two waveguide grating routers interconnected by a third waveguide grating, wherein waveguides comprising the third waveguide grating have unequal path lengths. In addition, the waveguides in the third grating are partitioned into sets of adjacent waveguides wherein each set corresponds to a particular wavelength band for the filter. The individual sets of waveguides are spaced at their connection to the second waveguide grating router such that optical signals within predetermined, different optical wavelength bands are routed to different output ports of the band filter. Some of the advantages of this novel band filter include compactness, sharp passband corners, low spectral ripple, and a lack of chromatic dispersion.

    Abstract: A variable bandwidth hierarchical OADM apparatus and method handles different data rates, based on a waveband OADM and one or more wavelength OADMs in parallel. The wavelength OADM combines multiple adjacent channels with fine granularity up to the bandwidth of the waveband OADM. The wavebands and wavelengths to be passed, dropped, and added by the hierarchical OADM apparatus are all electronically selectable, hence no hardware modification is needed when the data rate is changed. The use of a coarse granularity waveband OADM and variable-bandwidth wavelength OADM with fine granularity enables our hierarchical OADM apparatus and method to provide a variable-bandwidth multi-granularity add/drop capability.

    Abstract: Configurations for optical waveguide crossings are described. In one exemplary implementation, an optical chip includes waveguides integrated on the optical chip. The waveguides have varied widths dependent upon how many waveguides each of the waveguides cross with respect to each other. In another exemplary implementation, voids are inserted between waveguides in the vicinity of waveguide crossings of an optical device. The voids are configured to reduce optical losses in waveguides that have more waveguide crossing while simultaneously increasing optical losses in waveguides that have fewer waveguide crossings. Accordingly, the overall optical losses between the waveguides are generally equalized with respect to each other.
