It is shown that the delay time of a weak signal propagating in an amplifying medium on the wings of the spectral amplification line may be shorter than the time of propagation of the signal with the velocity of light in vacuum. It is found that in this case, the time dependence of the signal is exactly 'reconstructed' at the point of detection, and the detection of the signal continues even if it is abruptly terminated at the point of transmission. It is also shown that using the complex time of group delay of the signal, it is possible to improve the accuracy of the results in the first order of dispersion theory within this approximation.

We develop a quantization procedure for treating the propagation of light. This formalism is particularly effective in a dispersive nonlinear medium characterized by its macroscopic linear and nonlinear polarizability. We demonstrate it by analyzing the propagation of light in a multimode degenerate parametric amplifier.
