  6. Nonlinear directional coupler ( nldc ) is a switch used in optical network. w. s. man had studied transmission controlling with ground state soliton through nldc, it is obviously not available to used in superhigh speed network ; and mary j. potasek had studied the self - coupling with ultrashort solitons in nldc, self - coupling is difficult to control the signal transmitting. i has studied the transmission controlling with ultrashort solitons ( < 100fs ) in nldc, similarly i use a controlling pulse to control the signal pulse, it is the intensity of controlling pulse to decide the signal change its direction or not
