Abstract:
An optical switch may include a graphene layer to which incident light is applied; and a pump optical source for adjusting the transmittance of the incident light to the graphene layer by selectively applying pump light to the graphene layer. The incident light does not saturate the Fermi level of the graphene layer. The pump optical source determines the power of the pump light to allow the pump light to increase the Fermi level of the graphene layer to be higher than the energy level of the incident light. The optical switch changes the optical absorption of the graphene layer by adjusting lights applied to the graphene layer; and enables rapid control for lights in comparison with a conventional electronic control system.
