Abstract

We investigate the optical properties of (h11) and (110) InAs/GaAs heterostructures with built- in piezoelectrical fields. In both cases we find that the lateral structure of the quantum wells can decisively enhance the impact of the internal electric fields on their optical properties. In the first case this is due to the local screening of piezoelectric fields. In the second case it is the result of artificially introduced lateral piezofields. Both concepts open the way to a new class of semiconductor heterostructures with strong optical nonlinearities.
