Illustration of the telecom single-photon device. A resonant pulsed laser (top left) excites a single quantum dot embedded within a photonic-crystal waveguide, and the dot emits telecom-wavelength photons one at a time into the on-chip circuit. Gold contacts apply the bias that stabilizes the dot's charge environment.

Schematic comparison of carrier injection through a) 1 + 2 and b) 2 + 3 quantum interference within a semiconductor. The higher-order 2 + 3 process concentrates carriers into a narrower range of momentum-space directions and produces a more directional photocurrent.
