We use our vector Maxwell's nonlinear eigenmode solver to study thestationary solutions in 2D cross-section waveguides with Kerr nonlinear cores.This solver is based on the fixed power algorithm within the finite elementmethod. First, studying nonlinear plasmonic slot waveguides, we demonstratethat, even in the low power regime, 1D studies may not provide accurate andmeaningfull results compared to 2D ones. Second, we study at high powers thelink between the nonlinear parameter $\gamma_{nl}$ and the change of thenonlinear propagation constant $\Delta \beta$. Third, for a specific type ofphotonic crystal fiber, we show that a non-trivial interplay between theband-gap edge and the nonlinearity takes place.
