We demonstrate a novel all-optical spatial Light modulator capable of megahertz modulation rates. It is based on the quantum-confined Stark effect, but the modulating electric field is entirely photogenerated by strongly asymmetric photocarrier transfer in ...
By comparing photoluminescence and photo reflectance spectra taken on a series of InGaN-GaN quantum wells grown under identical conditions except the growth time of the InGaN layers, we could monitor the Quantum Confined Stark Effect (QCSE) without changin ...
We show that the two-dimensional quantum confined Stark effect in a semiconductor quantum wire can display novel behaviour, i.e. wave function splitting and cascading. No analog to these phenomena can be found in bulk material or quantum wells. The consequ ...
