Abstract

We discuss the maximum achievable time delay of stimulated-Brillouin-scattering-based systems that rely on the superposition of gain and loss spectra. As we will show, the time delay can be enhanced up to 8.5 times if the gain is superimposed with a broad loss and 9.5 times if two narrow losses are superimposed at the wings of the gain. Furthermore, we show that the parametric interaction between the different pump waves is negligibly small. Our theoretical analysis does not include pulse distortions that are accompanied by the delay.

Figures (2)

Fig. 1
Fig. 1

Maximum time-delay gain and time delay for a Lorentzian gain (solid curve and inset a), a gain superimposed with a three times broader loss (dotted curve and inset b), and a gain superimposed with two losses at its wings (dashed curve and inset c). Please note that only for the first case does the time-delay gain equal the amplification gain. The insets show the normalized gain as a function of the normalized frequency ( ω ω B ) γ with ω B as the frequency of the Brillouin shift and γ as the Brillouin gain linewidth.

Summarized power of all generated FWM products for a two- (dotted curve) and three-wave interaction (dashed curve). The insets show the optical output powers of the generated waves and the pump waves for the two- (inset a) and three-wave interactions (inset b) and a pulse input power of 60 dBm .
