We propose a novel way to actively control the propagation of THz Surface Plasmon Polariton (SPPs) in plasmonic waveguides structured on semiconductors. The SPP characteristics (field confinement and mode propagation length) can be precisely tuned by optically pumping charge carriers to the conduction band of the semiconductor. This approach can be used to generate active and integrated THz components and circuits.
