Abstract

We have studied the interaction of ~55-psec-duration soliton pulse pairs over thousands of kilometers of optical fiber with loss periodically compensated by Raman gain. We indeed observe the expected short-range, phase-dependent interaction. But we also observe a long-range, phase-independent interaction caused by dispersive-wave radiation from the solitons.

Microwave spectra of the intensity envelopes of 58-psec pulse pairs, initially separated by 270 psec (T0/τ = 4.66), recorded after 42 round trips of the loop (1752 km) for (a) the attractive phase (ϕ = 0) and (b) the repulsive phase (ϕ = π). The solid curves represent the calculated spectra of pulse pairs separated by 204 and 318 psec, in close agreement with the values of 197 and 311 psec, respectively, calculated from the theory of Gordon.2

Temporal separation of 57-psec pulse pairs as a function of fiber path length for T0/τ = 4.0 (squares), T0/τ = 6.0 (triangles), and T0/τ = 8.0 (circles). The filled symbols represent the repulsive-phase data, and the open symbols represent the attractive-phase data. The solid curves are calculated from the theory of Gordon.2
