Abstract
We present Beam Propagation Method studies of Second Harmonic Generation and nonlinear phase-changes by cascading in the Čerenkov regime. It is shown that cascading in the Čerenkov regime can produce phase changes comparable to those obtained by guided mode — guided mode interaction. The signature of cascading, with both positive and negative phase-changes is observed when the core refractive indices are varied. Large phase-shifts with small loss of the fundamental are shown to be possible.
