Abstract

We have studied the electroabsorptive properties of symmetrically strained (GaIn)As/Ga(PAs) superlattices consisting of 100 periods. Photocurrent measurements at 4 K reveal a pronounced pseudo-blue shift and a Wannier-Stark splitting of the heavy-hole exciton transition. A self-electro-optic effect device has been realized which makes use of the pseudo-blue shift due to the Wannier-Stark localization and of the transparency of the GaAs substrate. The self-electro-optic effect devices show on-off contrast ratios of 2.1 at 77 K and of 1.3 at room temperature.
