Abstract
We study numerically the tunable all-optical pulse compression induced by stimulated Brillouin scattering (SBS) double gain lines for Gaussian, super-Gaussian, and square shaped input pulses in optical fibers. We consider that the steepness of input pulse edges has an influence on the distortion and the broadening or compression factor of output pulses through the SBS-double-gain-line systems. For a Gaussian input pulse the distortion is relatively lower with the pulse compression ratio is only 0.75 in minimum. For a square input pulse the compression ratio can reach to 0.29 in minimum, but the distortion is highest.
