Abstract
We present measurements of the optical dipole of interband transitions in I nAs/GaAs quantum dots. Both the transmission in guided-wave geometry and th e in-plane polarization dependence of the photoluminescence are analyzed. T he relative oscillator strength and polarization of up to four optical tran sitions have been determined, and the electronic structure is discussed, wi th a focus on the heavy-hole versus light-hole character of valence states.
