Simultaneous fs pulse spectral broadening and third harmonic generation in highly nonlinear fibre : experiments and simulations

Résumé

Experiments and numerical simulations are used to study non-phasematched single-mode third harmonic generation occuring simultaneously with fs pulse spectral broadening in highly nonlinear fibre. Pump pulses around 100 fs at 1560 nm injected into sub-5 cm lengths of commercially-available highly nonlinear fibre are observed to undergo spectral broadening spanning over 700 nm at the - 30 dB level, and to simultaneously generate third harmonic radiation around 520 nm. Simulations based on a generalized nonlinear envelope equation are shown to well reproduce the spectral structure of the broadened pump pulses and the generated third harmonic signal.
