Effects of initial chirp of control pulse on soliton-repulsion logic gate

摘要

The effects of the initial chirp of the control soliton pulse on the time shift in the soliton-repulsion logic gate (SRLG) are investigated numerically by split-step Fourier transforms. We discuss the influence of both the positive initial chirp and the negative initial chirp to logic function of SRLG in two-core fibers. The results show that initial chirp of the control pulse seriously affects on the time shift. And the more initial chirp, the less the time shift.
