Abstract

In this paper, we show that Electromagnetically Induced Transparency (EIT) can be realized in mediums with Rydberg excitons. With realistic, reliable parameters which show good agreement with optical and electro-optical experiments, as well as the proper choice of Rydberg exciton states in the CuO crystal, we indicate how the EIT can be performed. The calculations show that, due to a large group index, one can expect the slowing down of a light pulse by a factor of about 10 4 in this medium.

摘要

在本文中，我们表明电磁诱导透明（EIT）可以在含有里德堡激子的介质中实现。通过与光学和电光实验结果高度吻合的现实、可靠参数，以及对CuO晶体中里德堡激子态的恰当选择，我们指出了如何实现EIT。计算结果表明，由于较大的群折射率，在这种介质中可以预期光脉冲减速约10^4倍。
