gdsfactory.cross_section.slot(width=0.5, layer='WG_ABSTRACT', slot_width=0.04, rail_layer='WG', sections=None, **kwargs)[source]#

Return CrossSection Slot (with an etched region in the center).

Parameters:

  • width (float) – main Section width (um) or function parameterized from 0 to 1. the width at t==0 is the width at the beginning of the Path. the width at t==1 is the width at the end.

  • layer (tuple[int, int] | str | int | LayerEnum) – main section layer.

  • slot_width (float) – in um.

  • rail_layer (tuple[int, int] | str | int | LayerEnum) – rail layer.

  • sections (tuple[Section, ...] | None) – list of Sections(width, offset, layer, ports).

  • kwargs (Any) – other cross section parameters.

Return type:

CrossSection

xs = gf.cross_section.slot(width=0.5, slot_width=0.05, layer='WG')
p = gf.path.arc(radius=10, angle=45)
c = p.extrude(xs)
c.plot()
