Description
technical field [0001] The invention belongs to the technical field of optical information, and in particular relates to an all-optical logic gate of an active nonlinear three-core optical fiber coupler. Background technique [0002] All-optical network (AON All Optical Network) means that the signal only undergoes electrical / optical and optical / electrical conversion when entering and leaving the network, and always exists in the form of light in the process of transmission and exchange in the network. The transmission and exchange of information in the all-optical network all use optical signals, and the intermediate optical-electrical and electrical-optical conversion processes are no longer required. Not affected by the slow response of electronic equipment in the original network, it is an ideal choice for the next generation network. [0003] In the realization process of all-optical network, optical logic gate is the key device to realize high-speed optical packet swi...
