S-parameter Element in Ansys Lumerical INTERCONNECT — Lesson 2

Creating an S-Parameter Element

S-parameters describe the frequency-dependent responses for all input and output port combinations and polarizations. In this video lesson, you will learn how to use the S-parameter primitive elements available in the Element Library.

Demo

The following video demonstrates how to set up and load data into an Optical N Port S-Parameter element from a component-level simulation of a Y-branch in FDTD.
The S-parameter data file loaded in this demonstration can be downloaded here.

The project file created at the end of the video can be downloaded here.

Advanced: S-Parameters with Group Delay

The phase of long waveguides changes quickly as a function of frequency due to the group delay. In this video lesson, you will learn about an alternative method for formatting the S-parameter file data to isolate it and make it work for long devices.
