Electromodulation of the electronic structure and optical properties of

Abstract

We show that large, linear electrooptic coefficients are expected in strained-layer superlattices grown along the (111) axis. The linear electrooptic effects in these superlattices are due to the large, piezoelectrically generated internal electric fields which occur in them. Such linear electrooptic coefficients are not expected in lattice matched superlattices or superlattices grown along (100).
