Abstract: Dynamic microcavities may arise when extremely short light pulses collide in a resonant medium. Such structures are of interest for the creation of ultrafast optical switches and optical memory cells. In early studies, it was shown that the particle concentration strongly affects the shape of dynamic microresonators - with increasing particle density, the shape of such structures is distorted. In this paper, based on the numerical solution of the Maxwell–Bloch equations, the possibility of creating non-blurred dynamic microresonators in a dense three-level medium is shown.

Keywords: extremely short pulses, attosecond pulses, dynamic microresonators, optical switching, optical memory.
