An essential device in opto-electronics is the optical waveguide. In the following we present a way to incorporate a waveguide field source into numerical time-domain simulations via the total field/scattered field technique. In particular, we develop a method by which we introduce a Gaussian light-pulse with the real eigenmodes of a slab waveguide into the nodal discontinuous Galerkin time-domain scheme.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
