Abstract

In this paper we study the thin taper optical wave guide structure by using the step discontinuity model. The technique presented is unique and not being discussed elsewhere. We study the power loss and effect on mode field pattern due to step discontinuity for the case of symmetric single mode planar taper wave guide structure. The only assumption, we consider is that there are no reflection of fields at the step discontinuity point. In this paper we also assume that there are no mode conversions due to discontinuity effect and the structure maintain the single mode operation even at the step discontinuity point. We deliberately considered the thin taper structure to be valid on single mode operation. The technique presented can be easily extended to more complicated wave guide structure like asymmetric wave guide structure, ridge wave guide structure etc.
