Paper Abstract

Temporal effects of the optical phase conjugation in dispersion-shifted fibers and in semiconductor laser amplifiers are numerically shown. In dispersion-shifted fibers, the frequency chirping is induced in the conjugate pulse by the signal pulse and pump wave through the cross-phase modulation, which increases with the signal power. In semiconductor laser amplifiers, the conjugate pulse has distortion and frequency chirping due to the amplified spontaneous emission noise and the carrier depletion induced by the signal pulse. These effects can be reduced by increasing the pump power. By properly choosing the signal power and pump power, for both conjugators, the optical phase conjugations can be nearly ideal. Finally, the performances of the two conjugators are compared.
