摘要:

我们展示了一种技术来调整微柱腔的光学特性,通过在腔区域附近的样品表面上用强烈聚焦的激光束产生小缺陷。这种缺陷改变了结构中的应变,以可控的方式改变了双折射。我们应用该技术,使基腔模式的偏振退化和微调的整体模式的频率,需要在量子信息科学的应用。

英文摘要:

We demonstrate a technique to tune the optical properties of micropillar cavities by creating small defects on the sample surface near the cavity region with an intense focused laser beam. Such defects modify strain in the structure, changing the birefringence in a controllable way. We apply the technique to make the fundamental cavity mode polarization-degenerate and to fine tune the overall mode frequencies, as needed for applications in quantum information science.
