Abstract
We numerically investigated the transmission of a bunch of solitons resulting from the breakup of pulses with duration of several tens of picoseconds (ps) through a nonlinear optical loop mirror (NOLM) and found that under some conditions an individual soliton can be extracted. The NOLM selectivity can be adjusted by the amplification of the bunch of solitons before it is launched into the NOLM. The results demonstrate that an appropriate choice of the amplification and of the NOLM loop length makes it possible to extract one fundamental soliton and to tune the soliton duration. For a particular case of input pulses, the duration of the extracted soliton was tuned in the range between 0.23 and . We believe that the suggested method can be useful for producing solitons with desirable duration.
