Voltage-Controlled Scattering of Single Photons in a One-Dimensional Waveguide

We investigate theoretically the voltage-controlled single-photon transport properties in a one-dimensional waveguide. The transmission and reflection amplitudes are obtained by a full quantum-mechanical approach. It is revealed that one can control the single photon transmitted or reflected by adjusting the bias voltage. This scheme may have applications in the design of optoelectronic devices.
