Paper Abstract

The energy spectrum is considered of ultrathin active layer with the quantum well (QW) depth modulation in one or two lateral directions. It is shown, that the modulation can produce more or less sharp spectral peaks in the density-of-state (DOS) distribution. This is a transient case between 2D and lower- dimensionality carrier gases, which may be treated also as cases of coupled quantum-wires (QWr) or coupled quantum boxes (QB). It is shown that the DOS may be modified to place its peak just at the band edge to provide its involvement in the working optical transitions and, due to it, such structures have more low- threshold carrier concentration and stabilization of the operation wavelength comparing with ordinary quantum well structures.
