Refractive Index Description
The refractive index distribution can be specified in one of two ways:
-
An arbitrary refractive index profile can be uploaded as a
two-colum text file. The first column is the distance and the second column is the refractive index.

-
The refractive index can be created using a set of built-in linear functions. Each function
has the form f(y).
Multiple functions can be entered, and
most geometries of interest can be constructed this way. Click here for a complete description. The background index is assumed to be 1.0, and every function adds an
incremental value.
