摘要: The vector optical solitons composed of bright and dark pulses are analyzed. It is shown that in the small-amplitude limit a bound state these described by generalized Zakharov system, which supports coupled soliton solutions, under special conditions it reduces to an integrable model. In model approximation valid, numerical simulations show rather stable states as well their almost elastic collision.
