In this paper, we discuss multihop optical bus interconnection networks. For massive parallel computing systems, such interconnection can interconnect a large number of processing elements and reduce system latency at the same time. We give the qualitative results of De Bruijn bus network and Kautz bus network as an engineering options based on combinatorial hypergraph theory and a uniform alphabetic constructive method. We also give an implementation method via polymer based waveguide holograms.
