Nondegenerate optical parametric amplif iers can be used to simultaneously phase conjugate and amplify a pulse in a nonlinear optical fiber. The gain in the amplif iers compensates the linear loss in the fiber, while the phase conjugation effectively neutralizes second-order dispersion, self-phase modulation, the Raman selffrequency shift, and Gordon–Haus jitter. If the remaining third-order and nonlinear dispersions balance, solitonlike pulses are able to propagate with subpicosecond pulse widths.
