Abstract

We study the supercontinuum generation in a nonlinear
silica single layer plasmonic waveguide. A major part of
spectral broadening is related to soliton dynamics when an
ultra-short pulse is launched in waveguide with anomalous
GVD. Production of supercontinuum with 10th, 15th and
30th, orders bright solitons by considering all the nonlinear
effects and dispersions i.e., inter-pulse Raman scattering,
self-steepening, self-phase modulation, cross phase
modulation, which indicates the existence of a
supercontinuum propagation about 20 times broadening
than initial width of input spectrum.
Also, we consider the absorption effect of plasmonic
waveguide by calculating propagation length from
propagation constant. The propagation length of plasmonic
is compared with the waveguide length and nonlinear
length. At wavelength 1.22μm, the propagation length is
obtained in the order of waveguide length which means one
can consider the effect of absorption cannot alter the
results. The nonlinear plasmonic waveguides are suitable
for integrated photonics because of subwavelength
confinement of plasmonic waveguides.
