Xsection gauss4/12/2023 Nd.add_layer2xsection(xsection='XS1', layer='L1') A default accuracy will be used if the call omits a value. The layer has an “accuracy” attribute that describes its resolution in the mask layout in um. The growx keyword is used to describe the symmetrical widening of the guide with respect the default width, where the value represents the growth per side. Below is an example of a xsection having 3 mask layers. An example of this concept is a waveguide of a specific width and a trench layer that is a wider version of the waveguide. However, it is possible to grow the width of layers when adding them to a xsection. Nazca allows you to do it all at once, as it will automatically create xsections and layers it hasn’t encountered earlier.īy default, a layer in a xsection will have a certain width. To make this all work we need to define a xsection, one or more layers, and add layers to the xsection. By added one or more layers to a xsection (cross section) object it becomes possible to draw those layers at the same time in the context of the xsection. Many, if not most, waveguides and metal lines in a technology consist of more than one mask layer.
