2-D WDM OPTICAL INTERCONNECTIONS USING MULTIPLE-WAVELENGTH VCSELS FOR SIMULTANEOUS AND RECONFIGURABLE COMMUNICATION AMONG MANY PLANES

We propose and analyze a novel interconnection configuration in which one 2-dimensional plane can communicate simultaneously and reconfigurably with many planes by using WDM. This system incorporates arrays of multiple-wavelength VCSEL's as well as wavelength-selective detecting planes. High signal contrast ratio with low power penalty can be achieved for a channel separation > 30 nm, limited only by the detector spectral response. By using WDM pixels, the system capacity is significantly enhanced as compared to more traditional techniques.
