Paper Abstract

A variational wave function well suited to describe exciton dynamics in different confined geometries is used to compute the lowest exciton state in quantum well wires. The exciton quantization is studied as a function of lateral dimensions. The oscillator strength increases with the wire dimensions. In spite of this, the third-order nonlinear optical susceptibility, computed taking into account the exciton-exciton interaction and the phase-space filling mechanism, shows an opposite trend. Numerical results for CdS and GaAs samples are discussed.
