Photonics Systems Research Team
Group Outline and Primary Goal
The photonic systems research team is working on research and development of innovative photonic systems in a wide range of areas including optical integrated circuit technology, implementation and control technology, and quantum optics technology. We are not only conducting research and development into new integrated optical devices and implementation control technologies using silicon photonics as a platform from the user perspective, but are also working on vertical collaboration between areas such as proving new optical transmission and quantum optics technology utilizing these new devices and technologies through collaboration with other teams. We are working to create next-generation technology, promote innovation, and build an ecosystem through advances in unique technology under various public-private projects in addition to bridge-building activities such as the Silicon Photonics Consortium. We are also promoting fundamental research themes that could become the next foundation for photonic systems.
