Supercontinuum Generation in Silica Plasmonic Waveguide by Bright Soliton
We study the supercontinuum generation in a nonlinearsilica single layer plasmonic waveguide. A major part ofspectral broadening is related to soliton dynamics when anultra-short pulse is launched in waveguide with anomalousGVD.

| description | We study the supercontinuum generation in a nonlinearsilica single layer plasmonic waveguide. A major part ofspectral broadening is related to soliton dynamics when anultra-short pulse is launched in waveguide with anomalousGVD. Production of supercontinuum with 10th, 15th and30th, orders bright solitons by considering all the nonlineareffects and dispersions i.e., inter-pulse Raman scattering,self-steepening, self-phase modulation, cross phasemodulation, which indicates the existence of asupercontinuum propagation about 20 times broadeningthan initial width of input spectrum.Also, we consider the absorption effect of plasmonicwaveguide by calculating propagation length frompropagation constant. The propagation length of plasmonicis compared with the waveguide length and nonlinearlength. At wavelength 1.22μm, the propagation length isobtained in the order of waveguide length which means onecan consider the effect of absorption cannot alter theresults. The nonlinear plasmonic waveguides are suitablefor integrated photonics because of subwavelengthconfinement of plasmonic waveguides. |
