Dispersion-managed solitons in the net positive dispersion regime

We investigate some of the unique properties encountered by pulse solutions in a dispersion-managed optical fiber in the regime of net positive dispersion. Two pulse solutions of the same pulse width and different energies exist in this regime. Collisions of pulses of the same pulse width and different energies can lead to the destruction of the less-energetic pulse. Sideband generation can occur without a periodic phase-matching condition. The amplified spontaneous-emission-induced timing jitter follows a simple law that is expressible analytically. (C) 1999 Optical Society of America. [S0740-3224(99)02201-8].
