A branched nanowire with two input terminals and one output terminal can serve as a modulator. The light emission from the output resulting from illumination of one input can be modulated by illumination at the other input. The physical mechanism underlying the modulation is constructive or destructive interference of the nanowire plasmons supported by the structure. This finding is of importance for the development of integrated plasmonic devices for information and communication technologies.
