FIGURE 1. Atomic-force microscopy shows a QD array (InAs on GaAs) for emission at 1300 nm (left). Schematic diagram of conduction band of a single QD, simplified for clarity, shows only two sets of energy levels: 'ground state' (GS) and 'excited state' (ES), analogous to the atomic s and p shells (right).
