Optical and Quantum Electronics Aims and scope Submit manuscript

Abstract

Two different in-house software tools for numerical modelling of structures with a very high refractive index contrast and a strong χ (3) nonlinearity are briefly presented. Results of their application for modelling nonlinear nanophotonic and nanoplasmonic directional couplers based on slot waveguide geometry are successfully mutually compared and assessed.
