Material Dispersion Evaluation
Using Material Dispersion option it is possible to calculate the dispersion accumulated by a pulse passing through dispersive medium of the given thickness.
This option is available through Analysis > Material Dispersion
You need to specify the type of medium (it is taken from the Substrate database) and its thickness. If a combination of several media need to be analyzed, it can be performed with the help of Stack object.
In the case all Media specified in Stack object are considered.
Optionally it is possible to exclude the term (A + B*ω) from phase characteristic and constant term B from GD plot. These terms don't affect the GDD characteristic.
In the case all Media specified in Stack object are considered. Coatings (if they present) are ignored during Material Dispersion Evaluation.
|Important! Substrate object (Substrate + Thickness mode) or all Media in the Stack object (Stack mode) should be represented as formulas, since calculation of GD/GDD requires differentiation operations.|
