An electronic transportor that allows for the resonant tunneling of electrons between guided states, such as those found in a quantum wire or a line defect in a solid, and localized states, such as those found in a quantum dot or a point defect in a solid, using lateral coupling. In some embodiments, the transporter allows electrons of different energies to be transported to different ports of associated waveguides. In other embodiments, the transportor allows electrons of different energies to be transported at different phases.
