Policy

The explosively increasing demand for bandwidth in telecommunications and data-communication networks as well as the migration of major telecommunication markets to an open and competitive environment have created a need for reliable, flexible high-capacity networks. Wavelength division multiplexing (WDM) is put to practical use by the technological progress such as the optical amplifier, laser, and multi/demultiplexer. The WDM network is paid to attention as a technology that not only enables a great increase of the transmission capacity but also enables to make the all-optical network including the node function. In our laboratory, research is being done about the functional device which used three characteristics of "time" "space" "wavelength" for the optical communication system of the next generation and the optical information processing system.
