Abstract: | The formation of solitons upon compression of linearly chirped pulses in hollow-core photonic bandgap fibers is investigated
numerically. The dependence of soliton duration on the chirp and power of the input pulse and on the dispersion slope of the
fiber is investigated, and the validity of an approximate scaling relation is tested. It is concluded that compression of
input pulses of several ps duration and sub-MW peak power can lead to a formation of solitons with ∼100 fs duration and multi-megawatt
peak powers. The dispersion slope of realistic hollow-core fibers appears to be the main obstacle for forming still shorter
solitons. |
