We study the Gaussian pulse propagation and its absorption, dispersion, and distortion in an atomic medium for advanced optical technology. The output pulse intensity distribution in time and Rabi oscillations, as well as the phase of control fields, show significant dark and bright forms of soliton shapes. We investigate the localized intensity of dark and bright solitons with the intensity of control fields in time domain within the normal and anomalous group velocity dispersion regions. Uniform undistorted pulse intensity and bright soliton are noted in time domain with the phase variation of control fields. These theoretical results are useful for optical fibers due to their minimum losses of the signal quality.

我们研究先进光学技术在原子介质中的高斯脉冲传播及其吸收，分散和畸变。时间和Rabi振荡的输出脉冲强度分布以及控制场的相位显示出明显的暗和亮形式的孤子形状。我们调查正常和异常组速度色散区域内时域中暗和亮孤子的局部强度与控制场的强度。在时域中，随着控制场的相位变化，观察到均匀的未失真脉冲强度和明亮的孤子。这些理论结果对光纤有用，因为它们对信号质量的损失最小。
