Abstract
A theoretical study of the nonlinear propagation of picosecond chirped pulses in single-mode fibers is presented. We show that, under approp riate conditions, spectral narrowing-rather than broadening, as is gen erally believed-is induced, owing to the interplay of self-phase-modul ation and dispersion. For downchirped pulses at a wavelength of 0.9 mu m and a peak power as low as 0.1 W, substantial spectral narrowing occ urs.
