ABSTRACT
Four types of InGaAs quantum wire lateral superlattices, which are unstrained, or strained laterally, vertically, or uniformly, are investigated, respectively. Their optical properties such as optical gain and polarization dependence are quantitatively analyzed including the effects of the nonuniform strain distribution and the valence band intermixing using a two-dimensional finite-element method. The results show unique polarization dependence characteristics, which can be exploited either for the single polarization optoelectronic devices or for the polarization independent devices. Such results are compared with each other as well as the quantum wells.
