The evolution of an initial condition consisting of one soliton(like) pulse in one channel and no signal in the other channel of the coupler is investigated. We focus upon the energy transfer (switching) between the two channels as function of the energy of the signal. For decreasing energy the switching appears to take place for the first time in the energy region where the symmetric soliton solution of the coupler is unstable, and where at the same time an asymmetric stable soliton exists… CONTINUE READING
