摘要

只提供摘要形式。由于在半导体微腔中实现强激子-光子耦合的可能性，我们可以预期双激子也会被极化子效应强烈地修饰，从而形成双极化子。在这项工作中，我们研究了高质量量子阱(QW)微腔在T=5 K时的时间分辨泵浦探针光谱的非线性光学性质。样品由位于楔形/spl λ /-腔中心的25 nm GaAs单量子阱组成，具有AlAs-AlGaAs Bragg反射器。

Biexcitons or bipolaritons in a semiconductor microcavity?

Summary form only given. Due to the possibility of realizing strong exciton-photon coupling in semiconductor microcavities, one could expect that also biexcitons are strongly modified by polariton effects, leading to formation of bipolaritons. In this work, we have investigated the nonlinear optical properties of a high-quality quantum well (QW) microcavity in time-resolved pump-probe spectroscopy at T=5 K. The sample consists of a 25 nm GaAs single QW in the center of a wedged /spl lambda/-cavity with AlAs-AlGaAs Bragg reflectors.
