Abstract
Slow-light techniques are promising for obtaining tunable delay lines which are potential candidates for bit synchronization and buffer applications in optical packet switching networks. We describe a theoretical study on slowlight in optical fibers based on stimulated Brillouin scattering (SBS). A general model for resonant three-wave nonlinear interactions between a pump beam, an acoustic wave and a counterpropagating signal pulse is proposed. Analytic and numerical solutions of the three-wave coupled equations are obtained for the steady-state and the transient regimes, respectively. Space-time evolutions of a generating slow-light pulse for both small-signal and pump-depletion (or gainsaturation) cases in the above two regimes are given and compared, for different pump powers and signal pulse widths. The physical origin of broadening and distortion of slow-light pulse is discussed. Optimum design considerations for undistorted slow-light signal propagation also are discussed.
