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

本计画主要研究嵌入量子点的半导体微腔中的双光子过程。该项目的工作将集中在从双激子态通过光诱导虚态的下转换，导致腔增强的单光子发射。我们的联合理论和实验量子光学研究的目的是演示的受激下转换腔增强自发单光子发射的全光控制。该项目开创了基于量子光学原理的新一代非线性光子半导体器件。

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 aims for the demonstration of full optical control of cavity enhanced spontaneous single photon emission by stimulated down-conversion. The project pioneers new generations of nonlinear photonic semiconductor devices based on quantum optical principles.
