  • Bidirectional wavelength cross connect architectures using wavelength routing elements
    Patent number: 9223090
    Abstract: Bidirectional wavelength cross connects include a plurality of ports, each configured to receive an input optical signals, each input optical signal having a plurality of spectral bands. At least one of the plurality of ports is disposed to simultaneously transmit an output optical signal having at least one of the spectral bands. A plurality of wavelength routing elements are configured to selectively route input optical signal spectral bands to output optical signals.
    Type: Grant
    Filed: January 30, 2014
    Date of Patent: December 29, 2015
    Assignee: Altera Corporation
    Inventors: Edward J. Bortolini, Dirk Barthel, Robert T. Weverka, Samuel Paul Weaver, Paulo E. Silveira
