text: Solitons are localized waves formed by a balance of focusing and defocusing
effects. These nonlinear waves exist in diverse forms of matter yet exhibit similar
properties including stability, periodic recurrence and particle-like trajectories.
One important property is soliton fission, a process by which an energetic higher-order
soliton breaks apart due to dispersive or nonlinear perturbations. Here we demonstrate
through both experiment and theory that nonlinear photocarrier generation can
induce soliton fission. Using near-field measurements, we directly observe the
nonlinear spatial and temporal evolution of optical pulses in situ in a nanophotonic
semiconductor waveguide. We develop an analytic formalism describing the free-carrier
dispersion (FCD) perturbation and show the experiment exceeds the minimum threshold
by an order of magnitude. We confirm these observations with a numerical nonlinear
Schrödinger equation model. These results provide a fundamental explanation and
physical scaling of optical pulse evolution in free-carrier media and could enable
improved supercontinuum sources in gas based and integrated semiconductor waveguides.
