Extraction of a single soliton from a set of solitons by the use of a nonlinear optical loop mirror

摘要

We investigated numerically the transmission of a set of solitons through a nonlinear optical loop mirror (NOLM) and found that under some conditions a single soliton can be extracted. We analyzed the evolution of relatively long (20-50 ps) and no very strong (10 W) pulses. The results show that the input pulse duration and the amplification of the solitons resulting from pulse breakup play important role to extract the highest quality pulse. The transmitted pulses correspond to fundamental solitons with subpicosecond durations. We believe that the proposed method can be useful for the study of nonlinear phenomena in optical fibers.
