Abstract

Spectrally resolved and time-integrated four-wave mixing are used to measure the polarization dependence of biexcitonic signals and quantum beats between two-A-exciton (X_AX_AZ*) and A-biexciton (X_AX_A) states in a high-quality GaN epilayer. Mixed beats with two periods are observed: the first beating period corresponds to the energy splitting between X_AX_A*and X_AX_A; the second period corresponds to beating between A excitons (X_A) and donor bound excitons (D^OX). We also measure the polarization-dependent B-biexciton (X_BX_B) signal. The effective masses for the A and B holes are deduced from the binding energy.
