Coherent manipulation of vectorial soliton beam in sodium like atomic medium

A four-level, sodium like atomic medium, driven by a probe and control fields, is used to modify the paraxial vectorial light beam in the medium. A uniform packet of vector arrows is controlled, whose shape is stable and undistorted during propagation, known as vectorial soliton. To the best of our knowledge, significant control over vectorial soliton is reported for the first time in the present work. Optical vectorial solitonic beams are controlled and manipulated with the parameters of the coupled fields with the system. The vectorial soliton is a strong, undistorted function of detunings, Rabi frequencies, and collective phase of the deriving fields, respectively. The modified vectorial solitons may have useful applications in telecommunication technology for delivering data bit streams over long distances and data processing.
