WDM cross-connected star topology for the bilayered ShuffleNet

A WDM cross-connect is a device based on integrating a two-dimensional array of Bragg diffraction cells. This device can be used in various wavelength routing network applications and it overcomes the major problems related to a conventional broadcast passive star coupler. In this paper, we propose a method of using this device in the implementation of a new logical topology: the bilayered ShuffleNet. This new configuration uses the same configuration as the conventional ShuffleNet, where N=kP/sup k/, but with the addition of another set of connections, the bilayered ShuffleNet achieves a higher efficiency compared to the conventional case. Moreover, the bilayered configuration offers additional flexibility. >
