There are reported the optical properties of novel quasi-zero-dimensional semiconductor structures obtained by self-assembly during the molecular beam epitaxy process. The studies has been focused on strongly asymmetric systems, called quantum dashes, quantum rods or columnar quantum dashes, and their potential applications in light sources or amplifiers for telecommunication and data transmission or single photon sources and other quantum electrodynamics based emitters. There is discussed the linear polarization degree of the edge emission of the columnar structures with respect to their potential for a polarization independent semiconductor optical amplifier at 1.55 μm. Additionally, there have been analyzed the photoluminescence spectra of single quantum dashes and single quantum rods in order to detect the exciton/biexciton emission, determine the biexciton binding energy and predict the exciton to biexciton radiative lifetimes ratio basing on a few level rate equation model.
