TRR 142 - Cavity enhanced two-photon physics with semiconductor quantum dots (A03)

This project is focused on two-photon processes in semiconductor microcavities with embedded quantum dots. The project work will be concentrated on the down-conversion from the biexciton state via an optically induced virtual state which leads to a cavity enhanced single photon emission. Our joint theoretical and experimental quantum optical study ...

TRR 142 - Ultrafast electric control of optical polarizations and transitions (C04)

The goal of this project is the development of photonic devices with nonlinear functionalities that can be controlled by electric means. The new functional structures involve an ultrafast electronic circuit which drives a single quantum dot in a microresonator. By ultrafast Stark effect tuning we will attain coherent control over the exciton and ...
