Enter the Scattering Matrix
The Amazing World of Scattering Matrices When starting to use Lumerical INTERCONNECT (or rival circuit-level simulation tools), the tutorials make clear enough the basic mechanics of the approach: Simulate a component in FDTD or MODE. Export an S-parameter file. Import it into INTERCONNECT. Build a larger photonic circuit. The workflow makes sense, but it often feels like we need a more satisfying answer to a simple question: What exactly is being stored in an S-matrix? ...
