We present numerical simulations of a logic gate based on repulsive interaction in a dual-core fiber and call it a soliton-repulsion logic gate (SRLG). The operation of the SRLG is compared with that of the conventional soliton-dragging logic gate based on cross-phase modulation. The length of the SRLG can be reduced by a factor of 3 over that of the conventional logic gate. By optimizing parameters, terahertz operation can be obtained.
