Bilayered ShuffleNet: a new logical configuration for multihop lightwave networks

Lightwave networks can be constructed by exploiting the capabilities of emerging optical technology. One of these technologies is the WDM cross-connect star coupler. This device based on integrating a two-dimensional array of Bragg diffraction cells, can be used in various wavelength routing network application to overcome the major problems related to the conventional star coupler. We propose a new logical topology, the bilayered ShuffleNet, which is shown to achieve higher efficiency compared to the conventional ShuffleNet. We also present a method of using the WDM cross-connect star coupler in the implementation of the bilayered ShuffleNet.<>
