Slab templates

The slab template defines the cross-sectional information about a slab waveguide: how it is drawn and what its optical modes are. The slab template is the essential component that needs to be defined in order to draw and simulate the Free Propagation Region of a star coupler.

You can use the following PCell to define slab templates:


Template for a slab (free propagation region) that stores the layer stack and modal properties of the slab.

In addition, slab templates will require a slab mode defined on them so you can model the free propagation region of the star couplers.


Simple slab model with first-order dispersion.


This Slab model interpolates the effective index between a given set of data points.
