Abstract We study the electromagnetically induced transparency (EIT) phenomenon in a hollow-core fibre filled with rubidium gas. We analyse the impact of the guiding effect and of the temperature on the properties of the EIT phenomenon. The refractive index felt by the probe laser is found to vary due to the radial dependence of the fibre mode field at the pump frequency. Several results are presented for the transmission, dispersion, and group velocity of the probe field, considering both the free propagation regime and the guided propagation along the hollow-core fibre. We note that the EIT occurring in a waveguide has a great potential for practical applications since it can be controlled by adjusting the gas and the fibre properties.

空芯微结构光纤中电磁感应透明度的建模和仿真

摘要 我们研究了充满铷气体的空心光纤中的电磁感应透明 (EIT) 现象。我们分析了引导效应和温度对 EIT 现象特性的影响。由于泵浦频率下光纤模场的径向相关性,探测激光器感受到的折射率会发生变化。考虑到自由传播方式和沿空芯光纤的引导传播,给出了探测场的传输、色散和群速度的几个结果。我们注意到波导中发生的 EIT 具有很大的实际应用潜力,因为它可以通过调整气体和光纤特性来控制。
