论文摘要
电磁诱导的透明度允许可控的吸收特性更改，可以在包括光量子存储器在内的许多应用中利用这些透明度。在本文中，我们介绍了$^{167} $ er的电磁引起的透明度的研究：$^6 $ liyf $ _4 $ Crystal在低磁场和超低温度下。实验测量方案采用光学矢量网络分析，提供了幅度，相位和脉冲延迟的高精度测量。我们发现，kelvin温度是研究该晶体在低场的电磁诱导透明度的必要要求。考虑到声子瓶颈效应，理论和实验之间达成了良好的一致性。
Electromagnetically induced transparency allows for controllable change of absorption properties which can be exploited in a number of applications including optical quantum memory. In this paper, we present a study of the electromagnetically induced transparency in $^{167}$Er:$^6$LiYF$_4$ crystal at low magnetic fields and ultra-low temperatures. Experimental measurement scheme employs optical vector network analysis which provides high precision measurement of amplitude, phase and pulse delay. We found that sub-Kelvin temperatures are the necessary requirement for studying electromagnetically induced transparency in this crystal at low fields. A good agreement between theory and experiment is achieved taking into account the phonon bottleneck effect.
