Multipulse storage and manipulation via solitonic solutions

Solutions to the Maxwell-Bloch equations for a. system are computed using the single-soliton Darboux transformation and the nonlinear superposition principle. These allow complete control of information deposited by a signal pulse (with the help of an auxiliary control pulse) in the coherence of the medium's ground states by injecting subsequential pulses. Additionally, we study the encoding of two signal pulses and their manipulation by a control pulse and show that multipulse storage and control are possible as long as the imprints made by encoding the signal pulses are sufficiently separated.
