Abstract

Ultrafast pulse shaping and ultrafast pulse spectral phase-retrieval techniques are used in the spectral interference measurement of nonlinear pulse propagation dynamics in dispersion-shifted optical fiber. Nonlinear responses in both amplitude profile and phase profile of the pulses at zero-dispersion wavelength as well as at nonzero-dispersion wavelength are directly measured. A numerical simulation that uses a third-oder-dispersion-included nonlinear Schrödinger equation gives excellent agreement with the experimental data.

Fig. 1

Pulse spectra before and after the 4-km DS fiber transmission and retrieved nonlinear phase responses. The pulses are centered at wavelengths of 1542 and 1567 nm (two separate experiments are shown), on either side of the zero-dispersion wavelength of 1550 nm. Inset, a phase-coherently delayed pair of a strong pulse and a weak pulse can be generated simply by use of a nonwedged beam splitter.

Fig. 2

Pulse spectra before and after the 4-km DS fiber transmission and the retrieved nonlinear phase profile for pulses centered at the zero-dispersion wavelength of 1550 nm (where the group-velocity dispersion parameter D is approximately zero). The splitting of the pulse spectrum is the characteristic response to the coupling between the third-order dispersion and the SPM in the fiber.

Fig. 3
Fig. 3

Pulse propagation simulation at the zero-dispersion wavelength of the fiber. The simulation results are shown along with the experimental results for comparison. The beats in the spectra are removed by gating away of the weak pulse numerically. The agreement is excellent.
