Abstract

We measure the polarization dependence of four-wave mixing (FWM) signals in highly-stacked InAs quantum dots on an InP(311)B substrate. Dephasing time T2 and FWM signal intensity show large anisotropy for the crystal axes. The measured T2 is determined only by the exciton population lifetime, and thus the polarization dependence of T2 reflects the difference of the transition dipole moments related to bright exciton states with orthogonally linear polarizations.
