The Core Researcher is Professor Yasuhiko Arakawa, who heads the project. The researchers join PECST from three groups, representing Industry, Academia and Government, where PETRA represents industries, University of Tokyo represents a group of universities, and AIST represents national laboratories. Those researchers cross organizational boundaries to further research into each topic, utilizing the strengths of these different backgrounds.

In order to realize PhotonicsElectronics convergence systems, it is necessary to not only develop innovative technologies such as silicon light emitters, but also to clear the way to market by demonstration of a system. This project promotes research and development of these innovative technologies for photonics-electronics convergence in order to realize an “On-chip data Center” – a data center integrated on a chip by 2025.

Activity Report 1

Activity Report 2

We demonstrated, for the first time, optical interconnects integrated with 13-channel array laser, silicon optical modulator and germanium photodetector on a single silicon substrate with 5mm×4.5mm chip size. A 5 Gbps line bit rate and 3.5 Tbps/cm2 transmission density were achieved. This technology will solve the bandwidth bottleneck among LSI chips in the future.

As on-chip light sources, quantum dot lasers have several advantages such as high temperature stability. We have demonstrated InAs/GaAs quantum dot lasers on Si substrates by means of semiconductor wafer bonding and layer transfer. Our laser emits at 1.3 μm with a threshold current density of 205 A/cm2, the lowest of any kind of laser on silicon reported to date.

Research Goal In order to overcome the limits of LSI by converging electronics and photonics technologies, the PECST will aim to mount leading-edge LSIs on ultra-dense photonic integrated circuits (10Tbps/cm2), which we call, “LSI-on-photonics-

10 G

integration circuits”. In addition, we will explore innovative photonic devices based on nanotechnology through strong collaboration between industry and academia. As a result, the PECST will contribute to develop future technologies for the photonics- electronics convergence system. In all these activities, the PECST will make clear the prospects for industrialization through technological demonstration of photonic integrated circuits, and to develop basic technologies for realizing nanotechnology based innovative systems. Above all, the PECST would like to contribute to the development of a safe, secure and comfortable society, and also contribute to the solution of environment, resource and energy issues, as well as enhance international competitiveness of industry.
