class kqcircuits.elements.waveguide_coplanar_straight.WaveguideCoplanarStraight

Bases: Element

The PCell declaration of a straight segment of a coplanar waveguide.

static build_geometry(element, trans, l)

static add_waveguide_path(element, path: DPath, shape: DPolygon)

Inserts the path and the shape to ‘waveguide_path’ layer. If element.add_metal is True, inserts the shape to ‘base_metal_addition’ layer.

Prefer this function to add path on a waveguide trace.

The path is used only for computing waveguide length and the path width should be zero to not mess up the shapes in ‘waveguide_path’ layer.

Parameters:

• element – An instance of a waveguide coplanar class.

• path – The path along the centerline of the waveguide with zero width.

• shape – The shape of the waveguide trace.

build()

Child classes re-define this method to build the PCell.

PCell parameters:

• l (Double) - Length, default=30

• add_metal (Boolean) - Add trace in base metal addition too, default=False

• ground_grid_in_trace (Boolean) - Add ground grid also to the waveguide, default=False
