Coincident pulse techniques for multiprocessor interconnection structures

We present several optical interconnection structures which support communication requirements unique to multiprocessor systems, namely, broadcasting, multicasting, simulcasting, and multiport memory access. The structures are based on guided wave time division multiplexed channels and use coincident pulse techniques to optically demultiplex individual bits at selected destinations. We describe 1-and 2-D structures which are appropriate for processor to processor interconnections and for processor to memory interconnections, respectively.
