The optical cross-connect (OXC) system described in this paper increases the operation flexibility and reliability of the trunk-line optical networks used for data communication. It features an OXC node comprised of a photonic switching network and a conventional electric switching network that are connected hierarchically. The operation and management(More)
Radio waves incident to electromagnetic absorbers have been experimentally visualized for the first time, which has been accomplished by the real-time visualization method for high-frequency electric field distributions: the live electrooptic imaging technique. Imaged have been electromagnetic reflections, refractions, and standing wave formations at sheet(More)
Electromagnetic waves propagating in air are visually observed with phase evolution in real time by live electro-optic imaging technique. We show how geometrical and crystallographic arrangements of an electro-optic sensor plate enable the realization of the real-time visual observation of traveling 100-GHz electromagnetic waves. For this purpose, a(More)
Asynchronous operation of the live electrooptic imaging technique has been newly proposed and successfully demonstrated, which drastically untightens the severe restrictions regarding synchronization and modulation bandwidth in its conventional master-mode operations. The new operation mode is enabled by generation of an optical LO signal as a(More)
