A multiple quantum well device has a wide well and a plurality of narrower wells spaced from each other and sandwiched between a plurality of barriers and with quantum coupling existing between the wells. Semiconductor substrates and optimal well and barrier widths are selected to yield band gaps and charge localization within the wells such that the energy differences between the ground state of the wide well and the N excited states of a narrow wells correspond to the energy of a photon in the desired spectral range.
