Multiwave interconnection networks for MCM-based parallel processing
This paper presents multiwave interconnections — optical interconnections that employ wavelength components as multiplexable information carriers — for next-generation multiprocessor systems using MCM technology. A hypercube-based multiprocessor network called the multiwave hypercube (MWHC) is introduced, where multiwave interconnections provide highly-flexible dynamic communication channels. A performance analysis shows that the use of integrated multiwave optics enables the reduction of network complexity on a MCM substrate, while supporting low-latency message routing.
In this paper, we also present the experimental fabrication of wavelength detectors for the proposed system, and discuss the physical limit on the number of wavelength components at the present state of technology.
