Abstract: Disclosed are an apparatus for generating/detecting a terahertz wave using graphene and a method for manufacturing the same. The apparatus for generating/detecting a terahertz wave includes a substrate which has an active region and a transmission region, a lower metal layer which is extended in a first direction on the active region and the transmission region of the substrate, a graphene layer which is arranged on the lower metal layer of the active region, and an upper metal layers which are extended in the first direction on the substrate of the transmission region and the graphene layer of the active region. Here, a terahertz wave can be generated or amplified by surface plasmon polaritons which are induced at the boundary surface between the lower metal layer and the graphene layer by a non-tilt laser beam which is applied to the graphene layer and the lower metal layer.
