Taper#

class zeroheliumkit.src.geometries.Taper(length: float, layers: dict = None, alabel: tuple = None, extension_sizes: tuple = (0, 0))[source]#

Bases: ArbitraryLine

Represents a multilayer Taper geometry.

Parameters:

  • length (float) – length of the tapered section

  • layers (dict, optional) – layer info. Dictionary values must be a (input width, output width) tuple. Defaults to None.

  • alabel (tuple, optional) – labels of the start and end-points. Defaults to None.

Examples

>>> length = 10.0
>>> layers = {'layer1': (0.1, 0.2), 'layer2': (0.2, 0.5)}
>>> alabel = ('start', 'end')
>>> taper = Taper(length, layers, alabel)

Methods

add(layer)

Adds a layer to the class with the given name and geometry.

append(structure[, anchoring, ...])

Appends an Entity or Structure to the Structure.

clean()

Removes all layers with empty polygons

copy([rename_anchors, with_suffix])

Creates a deep copy of the Entity instance.

crop(geom[, loc])

Crops polygons in all layers.

cut(geom[, loc])

Cuts the specified polygon from polygons in all layers.

export_dict([remove_holes])

Returns all layer names and their corresponding geometries in a Dictionary.

export_dxf(filename, layer_cfg)

Exports layers as a DXF file.

export_gds(filename, layer_cfg)

Exports all layers as a GDS file.

export_pickle(filename)

Exports all layers as a pickle file.

get(lname)

Retrieves a layer by its name.

has_layer(name)

Check if a layer exists in the class.

mirror(aroundaxis[, keep_original, ...])

Mirror all objects around a specified axis.

move(dx, dy)

Moves all objects in the class by the specified (dx, dy) offset.

quickplot([size, color_config, zoom, ...])

Plots the Entity object with predefined colors for each layer.

remove(lname)

Removes a layer from the class.

rename(old, new)

return_mirrored(aroundaxis, **kwargs)

Returns a mirrored copy of the Structure class.

rotate([angle, origin])

Rotates all objects in the class

scale([xfact, yfact, origin])
