Harmonic extended supercontinuum generation and carrier envelope phase dependent spectral broadening in silica nanowires.
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.
