experimentally investigate self-phase modulation (SPM) in silicon-on-insulator
waveguides and present insight into the interplay between SPM and
other nonlinear optical effects. Nonlinear interactions are studied
in waveguides with cross-sectional widths in the range 260 nm ≤ w ≤ 4150 nm, allowing for detailed study of the influence
of mode confinement on SPM. It is found that both the mode confinement
and peak intensity in the silicon waveguide are key in defining the
nonlinear interaction. Power-scaling trends in different spectral
ranges are presented, demonstrating the potential for multiple wavelength
nonlinear functionalities in a single device.
