title: Dynamics of solitons in coupled optical fibers.
abstract: The dynamics of soliton interaction in two tunnel-coupled optical fibers as a function of their phase difference Psi is analytically and numerically investigated. It is shown that if Psi = 0 or pi, no energy redistribution occurs in the fibers, and the soliton pulses either form a coupled state (Psi = pi) or repulse each other and separate during propagation (Psi = 0). Results of computer simulations under strong-coupling conditions are presented.
