Tóm tắt
Supercontinuum generation in silica-suspended
core fibers infiltrated with butanol has been analyzed numerically.
The spectra spanning from 806.19 to 1520.56 nm is
generated in #F1 fiber (D = 65.887 μm) with an all-normal
dispersion regime pumped by a 13.33 kW peak power
of laser source at 1.3 μm. With anomalous dispersion of
two closely lying zero dispersion wavelengths, #F2 fiber
(D = 67.494 μm) creates supercontinuum based on selfphased
modulation, phasematched four-wave mixing, and
no soliton fission as in the initial photonic crystal fibers
pumped in the anomalous dispersion region. A broad spectrum
of 629.12 nm is obtained when this fiber is excited at
the same wavelength as the #F1 fiber with a peak power of
12.5 kW. Butanol infiltration into three air holes significantly
improved the dispersion properties of the fibers, contributing
to supercontinuum generation advantage. The smooth,
noise-free supercontinuum spectrum can be compressed into
ultra-short pulses.
