摘要：
The propagation of a non-stationary light beam through a linear/non-linear discontinuity in a planar waveguide is considered by using an approximate approach based on the Generalised Non-Linear Schrodinger Equation (GNLSE) and the rigorous Transmission Line Modelling (TLM) Method. The objective is to compare the different theoretical approaches that can be used for the design of guiding structures with pulse shaping and signal processing functionality. Reflection and transmission of the light beam propagating through the junction of linear and non-linear waveguides are studied with respect to a dimensionless parameter that defines the increase of the refractive index induced by high-intensity radiation. In conclusion, the routes to efficient modelling are discussed.
