TRR 142 - Nonlinear optics in quantum dot molecules (C03)
In this project, nonlinear optical effects in InGaAs quantum dot molecules (QPM) are investigated. The goal is to use the QPM as a frequency converter. To this end, absorbed photons excite an exciton complex, which is transformed into another complex by applied voltage pulses on nanosecond and picosecond time scales as charges are transferred ...

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 ...
