Graphene-based optical switching system

The optical switch is a device used to turn on or off the optical circuit. It consists of mechanical, optical or electronic. In the network, we usually need to protect the switch to complete or interrupt the optical path. But traditional optical switches cannot identify the type of molecules. Due t...
