About the Center
AWAJI Yoshinari, Ph.D.
Director General
Information and telecommunications networks have become an indispensable infrastructure of modern society, and network services covering the world are supported by optical fiber communications. Japan's optical fiber penetration rate is among the highest in the world, and the abundant bandwidth enables the comfortable use of various network services and applications.
However, to steadily advance the development of future network services, such as the recently launched 5G service and beyond, the underlying optical fiber communication technology will be required to make even greater strides. For example, it is expected to support higher-volume data traffic, realize flexible and advanced network management, and provide a seamless bridge between optical fiber and high-performance wireless communication systems.
To realize these requirements, the Photonic ICT Research Center is engaged in cutting-edge research and development of technologies for ultra-high-capacity optical fiber networks utilizing the spatial and wavelength domains, technologies for using optical network resources more efficiently, and access technologies that integrate optical and wireless communications.
By collaborating with various research institutions in Japan and overseas, we are not only promoting the penetration and dissemination of these technologies, but also are contributing to the revitalization of the research community, as well as to the education of human resources that will constitute the next generation.
