S. Cortez et al., Polarization of the interband optical dipole in InAs/GaAs self-organized quantum dots - art. no. 233306, PHYS REV B, 6323(23), 2001, pp. 3306
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.
