Abstract
The quantum confined Pockels effect results from the combination of the gen uine interface roto-inversion asymmetry and the breakdown of quantum well i nversion symmetry due to the applied electric field. It is currently unders tood in terms of the field-dependent mixing of the heavy and light hole sta tes at the center of the minizone. Here we investigate how excitonic intera ction modifies the predictions of band-to-band calculations, and compare th eory with experimental results obtained in InxGa1-xAs-InP quantum wells.
