A Fabry-Perot interferometer was designed and built to perform high resolution spectroscopy of quantum dot optical transitions. The entire spectrum is measured using an experimental method utilizing the Fabry-Perot with a charge coupled device camera. Spectral broadening mechanisms are investigated using resonant and non-resonant excitation intensity dependence linewidth measurements. Dynamical nuclear-spin polarization is demonstrated in the absence of external magnetic field, by quasi-resonant circularly polarized intensity dependent optical excitation of a quantum dot containing one hole (the Overhauser effect).
