Abstract
In this work, we present an analytical model describing the density of states and spectral behavior of the ordered nanopore array diode laser. The nanopore structure consists of an ordinary quantum well perturbed by a periodic lattice of energy barriers. It is shown that such a perturbation leads to the formation of energy subbands in both the conduction and valence bands. The theoretically predicted gain spectrum shows excellent agreement with experimental results. Finally, the unique effects of in-plane quantization and periodicity on the intersubband selection rules are described in detail.
