Abstract
Exciton polaritons from the three uppermost valence bands and the lowest co nduction band in homoepitaxial GaN are studied by nonlinear spectroscopy. S econd and third harmonic generation and three-photon difference-frequency g eneration are used to excite resonances on different polariton branches. Th e resonances show a characteristic polarization dependence, which is consis tent with the symmetry assignment of the valence bands. (C) 2001 Elsevier S cience B.V. All rights reserved.
