摘要
我们对不同铯原子汽室空间中,电磁诱导吸收(EIA)与电磁诱导透明(EIT)特性进行了比较。通过理论模拟原子在不同多普勒背景下的周期性吸收调制与原子相干效应的关系,表明在狭小空间下的原子,其EIA效应较弱,EIT较强这一特性对应于介质可获得更好的周期性吸收调制,这一特性可用于改善原子汽室中的光子晶体特性。
Abstract
The quantum coherences of electromagnetically-induced absorption (EIA) and electromagnetically-induced transparency(EIT) of atoms placed in different space of vapor cell were compared.Based on the theoretical analysis of the dependence of absorption modulation on quantum coherence in different vapor cell with different Doppler width, we found that the EIA decreased, while the EIT increased, leading to the improvement of absorption modulation, which can be used to improve the property of photonic crystal in confined space of atoms.
