Photonic switching method and photonic switch utilizing same

摘要

A photonic switching method and a photonic switch utilizing the method are disclosed. Input electrical signals Ea DIFFERENCE Ed are input through plural input ports 21a DIFFERENCE 21d are converted into optical signals with the pulse intervals of these input electrical signals being preserved unchanged. The converted optical signals are timing adjusted within the pulse interval and multiplexed in such a manner that these optical signals do not overlap with each other on the time axis. The resulting multiplexed optical signals are transferred to output ports 19a DIFFERENCE 19d. An optical signal, from among the multiplexed optical signals, which should be output at a target output port is separated by utilizing a mutual optical interactional function, for example, a four optical wave mixture.
