Abstract:
We experimentally study the dynamics of the generation of multiple sidebands by means of a quasi-phase-matched
four-wave mixing (FWM) process occurring in a dispersion-oscillating, highly nonlinear optical fiber. The fiber
under test is pumped by a ns microchip laser operating in the normal average group-velocity dispersion regime
and in the telecom C band. We reveal that the growth of higher-order sidebands is strongly influenced by the competition
with cascade FWMbetween the pump and the first-order quasi-phase matched sidebands. The properties of
these competing FWM processes are substantially affected when a partially coherent pump source is used, leading
to a drastic reduction of the average power needed for sideband generation.
