University of Tokyo to Develop Quantum-Dot Laser on a Silicon Chip

Intel and the University of Tokyo’s Institute for Nano Quantum Information Electronics have partnered for a research project based on optical inter-chip connection technologies. The research team has started their work on the project in December 2010.

The team will conduct research on the photonics/electronics fusion technologies field for inter-chip optical interconnects. As part of the project, they will develop a quantum-dot laser device on a silicon (Si) chip. It is challenging to develop lasers included into Si optical circuits by a cost-effective process.

Intel will offer US $500,000 to the University of Tokyo as a research grant for the three-year project. The university has already obtained US $142,000 from Intel for the first year.

The University of Tokyo’s Professor and Director of the Institute, Yasuhiko Arakawa stated that the university would apply for a patent if they achieved significant results. Arakawa added that however the university would not offer an exclusive license to Intel.
