摘要
We numerically study low-threshold supercontinuum generation using the significant enhancement of non-linearity in aqueous colloids with silver nanoparticles. We predict octave-spanning spectral broadening by femtosecond pulses with an intensity in the range of tens of GW/cm(2). The strong frequency dependence of the effective nonlinear coefficient of the composite significantly influences the spectral broadening by self-phase modulation and leads to a large blueshift of the spectra.
