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 biexciton transitions in a quantum dot. The project opens fundamentally new perspectives for nonlinear optoelectronic devices which are based on coherent electric control.

该项目的目标是开发具有非线性功能的光子器件，这些器件可以通过电气手段进行控制。新的功能结构涉及一个超快电子电路，它驱动微谐振器中的单个量子点。通过超快斯塔克效应调谐，我们可以实现对量子点中激子和双激子跃迁的相干控制。该项目为基于相干电控制的非线性光电器件开辟了全新的视角。
