Each line describes a separate layer of the index profile. There is no limit to the number of layers that can be used. The specification format must be followed exactly.
Each line represents a different layer. The layer description is as follows:
|thickness (um) | index(real or n) | index(imag or k) |
For example,
0.089 2.8 0
0.069 3.6 0
represents two layers with indices of 2.8 and 3.6 and thicknesses of 0.89um and 0.069um respectively. The materials have zero loss/gain.
Absorption is represented by a negative imgainary index and gain by a positive
imaginary number.
When using the dispersion data from an uploaded file, specify the column number
instead of giving a numeric value for the index.
For example,
0.089 a c
0.069 3.6 d
will interpolate the values from columns 'a', 'c' and 'd' and substitute those values
at the apporpriate wavelengths.
