1. Optical Information and Communication Technology
- Breakthrough in the Capacity Limit of Optical Communication: from Inter/Intra-Chip Interconnections to Global Networks -

An explosive increase in communication traffic is causing a serious anxiety that the capacity limit will be reached in the near future. We believe that the only solution for this issue is to create a seamless interconnection covering a wide area ranging from LSI chips to global backbone networks with a large-capacity optical transmission technology.

We are conducting research and development on short-range optical transmission technology inside and outside the information and communication equipment under the national R&D project of “Photonics Electronics Convergence Technology for Power-Reducing Jisso System.” This is one of the NEDO’s Future Pioneering Projects aiming at the development of ultrahigh-density information transmission systems. We are also collaborating with the Network Photonic Research Center of the AIST, which is responsible for the development of global networks. The Center is promoting the R&D project on optical path network technology called “Vertically Integrated Center for Technologies of Optical Routing toward Ideal Energy Savings” sponsored by the Ministry of Education, Culture, Sports, Science and Technology.
The other subjects we study include multicarrier light sources, photonic signal processing and measurement techniques as a basic research for the realization of the ultimate transmission capacity in the future networks.
