A novel light speed computing technology has been developed by NTT, Kyoto University, and Kyushu University that employs nanophotonic technology in critical paths and thus overcomes the problem of operational latency that is the chief limiting factor in conventional electronic circuits. The ultimate objective of this work is to develop an ultrahigh-speed optoelectronic arithmetic processor. This article provides an overview of our recent work and describes the successful implementation of this novel optical computing technology.
