TDM and TWDM de Bruijn networks and ShuffleNets for optical communications

We propose TDM/TWDM de Bruijn networks and ShuffleNets by utilizing small all-optical dilated slipped banyan networks, DSBs (Thompson, 1991). The proposed networks require fewer switches than DSBs, and smaller numbers of wavelengths than WDM de Bruijn networks and ShuffleNets. Furthermore, only one fixed-wavelength transmitter and one fixed-wavelength receiver are required for each node.
