Brings you to the World of Photonics!
Optical fiber networks have become an indispensable, if not always obvious, part of modern society. They support the ever-growing need for bandwidth to carry the increasing amount of information. In all forms of packetized voice, television broadcast, or data exchange, the growth is evident and the capacity of optical networks has to follow. The development takes place in all regions, from access, through metropolitan, to long-haul transmission. The boundaries of technology are pushed in the number of simultaneous optical channels, signal speed, and spectral efficiency. The deployment of systems operating at 40 Gbit/s and beyond joined with the increasing demand for flexibility and dynamic provisioning leads to the spread of domains of transparent transmission. This brings new challenges in the world of optical communication systems.

What's new...


Photonic Networks Laboratory (formerly Research Group of Advanced Communications Engineering) was found in April 1996. Since then, we have been engaging in the research activities and education of ultra high-speed optical communications and radio communications. Our recent interests include photonic backbone networks as well as radio access networks for multimidia communications in the next generation with larger capacity and higher quality.

Optical solitons are one of the promising candidates as a carrier in photonic backbone networks, that may enable ultra high-speed transmission for long distance. We are studying soliton transmission improvements by a theoretical approach as well as experimental. We are also interested in architectures of IP/WDM networks.

At the same time, we are studying intelligent radio systems in access networks that require a large flexibility. We consider the combination of multiple access technologies and intelligent signal processing will meet the expectance.

The current members include Prof. Ken-ichi Kitayama and A/Prof. Akihiro Maruta, and nearly 20 college students.
