Outline of Final Research Achievements

Making the best use of cutting-edge technologies such as; next-generation spatial division multiplexing on multiple-core fibers, scalable node architectures, advanced optical transmission that can maximally utilize frequency resources of fibers, and network architectures that enable transparent and seamless operations of national-wide and metro-area networks where transmission impairment is substantially reduced, we have achieved substantial network capacity enhancement, high energy efficiency, and excellent frequency utilization in photonic networks where routing operations are effectively conducted in the optical domain. Metrics in each technology, i.e. spatial multiplexing degree, maximum number of nodes that can be traversed by an optical path, maximum fiber degree of node, and frequency utilization efficiency has been substantially expanded so that they exceed the original target values. The product of the metrics yields 2,400 times of the present product value.

Academic Significance and Societal Importance of the Research Achievements

増加率が年率+20~30% (6.2~13.8倍/10年)にも達する通信トラフィックを効率良く収容する次世代フォトニックネットワークが,現実的な装置コストおよび消費電力で構成できることを明らかにした.これにより将来にわたって発展可能な情報通信インフラストラクチャの実現可能性を示した.
