    摘要： A photonic network includes a plurality of nodes each supporting add and drop of at least Y wavelengths, a plurality of optical links interconnecting the plurality of nodes, the plurality of optical links support up to X wavelengths and Y≦X, an optical routing protocol configured to compute a loop-free path through the plurality of nodes on the plurality of links, the loop-free path is computed for one of the X wavelengths or a group of the X wavelengths using routing constructs adapted to a photonic domain, and optical components at each of the plurality of nodes configured to selectively block at least one of the X wavelengths based on the computed loop-free path. A photonic routing method and photonic node are also disclosed.

    摘要： An optical node includes an optical routing apparatus including N ports, N is an integer greater than 2, the optical routing apparatus configured to direct light that is input to each of the N ports to all of the other N ports, and a configurable optical blocking element located in line with at least one of the N ports. A method includes broadcasting a plurality of optical signals over a plurality of ports using a broadcast element, selectively receiving a desired signal from all of the plurality of optical signals at one of the plurality of ports, and blocking the plurality of signals via a blocking element in line with one of the plurality of ports thereby preventing a multiple path of the broadcast plurality of optical signals.
