Polarization dependence of femtosecond soliton-soliton interactions in dispersion-shifted fiber.
The polarization dependence of femtosecond soliton-soliton interaction in a dispersion-shifted fiber has been investigated in detail theoretically and experimentally. For 400-fs soliton pulses the input pulse separation at which the soliton-soliton interaction occurs is 1.6 ps for orthogonally polarized solitons as opposed to 2.3 ps when the polarizations are parallel. Similar to that in the parallel condition, the soliton self-frequency shift in the orthogonal case is accelerated through soliton-soliton interaction. However, the magnitude of the soliton self-frequency shift is reduced to one third of that in the parallel condition.
