我们报告的方法制造的光子微结构，包含一个单一的磁性离子。将一个锰离子引入到位于ZnTe基微柱腔中的自组装CdTe量子点中。多步骤的制造过程包括分子束外延生长，光学特性，和聚焦离子束蚀刻。通过观察由于与锰离子的交换相互作用而分裂为六个的光谱激子线证实了该结构的实现。腔模通过温度的变化被调谐到量子点发射能量。所提出的技术被开发用于基于孤立掺杂剂的光电子学。
We report on the method of fabrication of a photonic microstructure that contains a single magnetic ion. Exactly one manganese ion was introduced into a self-assembled CdTe quantum dot, which was located in a ZnTe based micropillar cavity. The multistep fabrication procedure includes molecular beam epitaxy growth, optical characterization, and focused ion beam etching. Realization of the structure was confirmed by the observation of spectroscopic exciton lines split by six due to the exchange interaction with a manganese ion. The cavity mode was tuned to the quantum dot emission energy by a variation of the temperature. The presented technology is developed to be applied in optoelectronics based on solitary dopants.
