FIG. 1.

Signals and spectra: (a) The time-dependent signal of the pulse generated by an external pump; (b) describes the spectrum of the pulse; (c) the forward signal received outside the sample, where is is the distance from the center of the sample; (d) the spectrum of the forward signal; (e) the backscattering signal received at the center of the sample; and (f) the spectrum of the backscattering signal.

Spatial energy distributions and phase vector diagrams: (a) Describes the spatial energy distribution of the mode with , confined inside of the sample, whose localization length is ; the phase vector diagram (b) shows its perfect collective coherent behavior; (c), (e) are the spatial energy distributions of the modes with and , respectively, which lie outside the localized regime, where both are spatially extensive modes; and (d), (f) are phase vector diagrams of the modes with and , respectively, indicating that the collective coherent behavior has diminished.

Signals and spectra after the generated pulse has propagated for a long period of time: (a) The time-dependent forward residual signal received outside the sample, where is is the distance from the center of the sample; (b) describes the spectrum of the forward residual signal; (c) is the backscattering signal received inside the sample, where is is the distance from the center of the sample; and (d) is the spectrum of the backscattering residual signal.
