Advanced Optical Communication Technology, the Core of the Next-generation Ultrahigh-speed Communication Network
Aiming at spectacular advancement of information and communication networks
To realize spectacular advancement of information and communication networks of which the capacity has to increase by a factor of 1,000 in the next 20 years, we are working to develop photonic infrastructure technology that will be the core of next-generation ultrahigh-speed communication networks.
Content of research
We are studying new structured optical fibers to overcome the limitation of existing optical fibers, optical fiber application technologies to ensure safety and security, ultra-compact optical circuits to support opticalization, and optical simulators to support the design of optical fibers and optical circuits.
Multicore optical fiber (we are studying space-division multiplexing optical communication technology using multicore optical fiber, which has multiple cores in a single optical fiber.)
Silicon thin-wire optical waveguide devices (we are developing novel optical waveguides to make ultra-small optical wave circuits a reality.)
Multimode control technology (to achieve mode-multiplexed transmission, we are conducting research on mode multi/demultiplexer capable of multiplexing and separating transmission modes, and on technologies that can reduce mode-dependent characteristics.)
