摘要：

We estimate homogeneous broadening and shift of optical transition lines in self-assembled quantum dots (SAQD) caused by elastic Coulomb collisions of carriers in wetting layer with carriers in the SAQD. In particular, we demonstrate that the dephasing time for lasing transitions can be similar to 0.1-1 ps at carrier densities in wetting layer similar to 10(15) m(-2).
