Waveguide information to extrude a path between two CrossSection.
cladding_layers follow path shape
- Parameters:
cross_section1 – input cross_section.
cross_section2 – output cross_section.
width_type – sine or linear. Sets the type of width transition used if widths are different between the two input CrossSections.
- __init__(**data: Any) None #
Create a new model by parsing and validating input data from keyword arguments.
Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.
self is explicitly positional-only to allow self as a field name.
Methods
__init__
(**data)Create a new model by parsing and validating input data from keyword arguments.
add_bbox
(component[, top, bottom, right, left])Add bounding box layers to a component.
