Array waveguide grating (AWG)-based optical switching fabrics are receiving increasing attention due to their simplicity and good performance. However, AWGs are affected by coherent crosstalk that can significantly impair system operation when the same wavelength is used simultaneously on several input ports. To permit large port counts in a N × N AWG, a possible solution is to schedule...
Optical switching fabrics are gaining interest as in multi Terabit switching devices; the advantages over their electronic equivalents are mainly their information density and power consumption. Arrayed Waveguide Gratings (AWGs) are promising optical devices proposed by the academic and industrial community to build optical switching fabrics. Because of their wavelength routing property, AWGs allow...
The power consumption of large IP routers is increasing too fast with the increase of Internet traffic. This power consumption can be reduced if Optical Switching Fabrics (OSFs) are used instead of electronic backplanes and interconnects. And Arrayed Waveguide Gratings (AWGs) exhibit interesting properties for the design and implementation of OSFs. The paper studies how OSFs based upon AWGs scale...
Future Internet packet switches and routers will have to overcome intrinsic limitations of current electronic switching fabrics, related to the extremely high amount and density of the information to be internally processed, and the consequent very large number of interconnections, and very high power consumption and dissipation. Motivated by this observation, we consider different architectures of...
