  An effort was conducted to study temporal soliton pulse propagation in
silicon nano-waveguides. These nonlinear phenomenas were studied both
numerically and experimentally with phase-resolved Frequency Resolved Optical
Gating. Soliton pulse broadening, as well as pulse splitting from two-photon
absorption, was observed experimentally, and the simulations matched all of the
experimental results. Further simulations with the validated model have
demonstrated that compression can be observed in centimeter-length waveguides.
This study has demonstrated the feasibility of self-sustaining soliton pulse
propagation at substantially shorter length scales than optical fibers, which
offers much potential applications with regards to all-optical data transfer
and computing.
