Plasmonic all-optical switch and light control method using the same
A plasmonic all-optical switch includes a graphene layer, a first dielectric layer located on the graphene layer, a nano-antenna located on the first dielectric layer, and a second dielectric layer located on the nano-antenna. An incident beam is propagated by means of a surface plasmon wave generated at an interface between the graphene layer and the first dielectric layer. Further, localized surface plasmon resonance is selectively generated at an interface between the nano-antenna and the second dielectric layer by means of a pump beam incident to the nano-antenna to decrease an intensity of the incident beam. The plasmonic all-optical switch may operate at an ultrahigh speed just with a small light energy without any electric method, greatly reduce power consumption of an IT device by applying to an all-optical transistor or the like, and increase a processing rate.
