Gaussian Pulse Propagation via Bright and Dark Solitons through an Atomic Medium

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.
