Dynamics of the gap 2π pulse dynamics in one-dimensional resonantly absorbing Bragg gratings are studied. A new family of stable oscillating and excited unstable gap 2π pulses is analytically and numerically described by a transition from the two-wave Maxwell–Bloch equation to the modified sine-Gordon equation and by direct integration of the two-wave Maxwell–Bloch equation.
