摘要

我们将嵌入在pin二极管中的InAs量子点耦合到圆形bragg光栅，即靶心腔。我们观察到Purcell增强约为15倍，并且在量子点波长处腔反射率下降了80%。因此，这些器件有望作为量子网络中的单光子源和中继节点。

Dipole Induced Transparency and Large Purcell Enhancement in a Low Q Cavity

We couple InAs quantum dots embedded in a pinin diode to circular bragg gratings, i.e. bullseye cavities. We observe a large Purcell enhancement by a factor of about 15, and an 80% dip in the cavity reflectivity at the quantum dot wavelength. Thus, these devices are promising as single photon sources and repeater nodes in a quantum network.
