Abstract :
In this paper we present an analysis for the refraction of modes at the step discontinuity of a multimode slab waveguide. This analysis can be used analogous to ray tracing in conventional optics to obtain focusing properties of waveguide lenses. Apart from application in optical heads, this analysis finds application in communication systems that make widespread use of integrated optics.
