9. A 2D model makes some significant simplifications when applied to this problem- it cannot account for out of plane scattering and coupling to substrate modes. Complex interactions between the loss mechanisms cannot be ruled out, however, the model shows good agreement with the experiment (2nm difference in shifts), suggesting that, these interactions do not have a significant effect. The small discrepancy is probably due to absence of these effects in the simulation.

12. g) is negligible. This is reasonable in the SOI system at this wavelength.
13. This makes the non-trivial assumption that disorder does not change the group velocity. In order to verify this, we ran simulations of pulses propagating through the disorder. We found that up to the group indices where pulses break up due to dispersion (n>16), there was only minimal, differences in group velocity between normal and disordered W1 waveguides.
