Numerical simulations are used to study the interaction dynamics
between pump spectral broadening and third harmonic generation during
supercontinuum generation in a highly nonlinear fused silica nanowire
using sub-100 fs pump pulses. In particular, we show that the
superposition of the generated third harmonic with the
spectrally-broadened pump pulse exhibits significant dependence on the
input pump carrier envelope phase, and we examine this dependence as a
function of pulse duration and propagation distance.
