Abstract

The timing restrictions for soliton dragging logic gates (SDLG)¹ can be relaxed by asymmetrizing the interaction between the orthogonally polarized control and signal pulses. In particular, by prechirping the signal pulse in a normal group velocity dispersion fiber, we find experimentally that the timing restriction can be loosened from less than two pulse widths to over 3.3 pulse widths. For this passive prechirper arrangement, the timing restrictions are loosened at the expense of increased minimum switching energy.
