Sketch of (a) atom–nanowires coupling system and (b) its potential application as optically controllable switch and (c) optical transistor. Two gray terminated lines in panel (a) represent two terminated nanowires and the small red circle is a two-level emitter asymmetrically coupled to two nanowires. Gray rectangle in panel (b) and gray circle in panel (c) represent atom–nanowires setup, respectively.
