Abstract
The influence of permanent dipole moments of quantized states on intersubba nd second harmonic generation based on quantum-interference induced transpa rency in semiconductor quantum wells is explored using the harmonic balance method. The permanent moments are found to be quite important: they affect the transparency condition, especially at larger pump intensities. Hence, both the conversion efficiency and the optimal interaction path length chan ge significantly when accounting for the permanent moments, and the convers ion efficiency is reduced.
