Abstract

In optical communication systems, the use of alternating dispersion is a common way to deal with bit-rate limitations caused by dispersive pulse broadening. An alternative to this technique was proposed by Yariv et al[1] some time ago. It was suggested that a phase-conjugate conversion of the signal at the middle of the propagation length would cancel, at the line output, the accumulated dispersive effects over the first half propagation. Although more complicated than the first technique, this approach has the advantage of also being able to compensate for the self-phase modulation effects incurred through the Kerr nonlinearity of silica fibers, as first demonstrated experimentally by Watanabe et al[2].
