摘要:

材料应变作为控制嵌入在固态环境中的量子发射体的能级的补充资源,近来受到越来越多的关注。一些稀土离子掺杂剂提供同时具有窄线宽和对应变高度敏感的光学转变。在这样的系统中,光谱烧孔技术(其中在大的不均匀轮廓内烧透明窗口)允许受益于窄的特征,其也对应变敏感,同时与大的离子集合一起工作。然而,与系综一起工作可能会引起不同离子之间的不均匀响应。我们的实验研究如何修改由于外部机械应变,特别是一个狭窄的光谱孔的形状,作为一个函数的几何形状的晶体网站和晶轴的应力施加的孔加宽。研究这些效应是必不可少的,以优化现有的应用领域,已经从这些掺杂剂,如频率计量学和量子信息处理,更完善的相干性的利润,稀土掺杂晶体,甚至建议这些材料的新的应用,例如作为强大的设备力传感或高灵敏度加速度计。

英文摘要:

Material strain has recently received growing attention as a complementary resource to control the energy levels of quantum emitters embedded inside a solid-state environment. Some rare-earth ion dopants provide an optical transition which simultaneously has a narrow linewidth and is highly sensitive to strain. In such systems, the technique of spectral hole burning, in which a transparent window is burnt within the large inhomogeneous profile, allows to benefit from the narrow features, which are also sensitive to strain, while working with large ensembles of ions. However, working with ensembles may give rise to inhomogeneous responses among different ions. We investigate experimentally how the shape of a narrow spectral hole is modified due to external mechanical strain, in particular, the hole broadening as a function of the geometry of the crystal sites and the crystalline axis along which the stress is applied. Studying these effects are essential in order to optimize the existing applications of rare-earth doped crystals in fields which already profit from the more well-established coherence properties of these dopants such as frequency metrology and quantum information processing, or even suggest novel applications of these materials, for example as robust devices for force-sensing or highly sensitive accelerometers.
